The castle of Rhodes (which actually is a complete medieval city surrounded to this day by walls) is one of the best-preserved and most historical castles of the world.

It took its current form mostly in the period when the knights of the Order of Saint John occupied the island, from 1309 until 1522. Among other things, it was the location where one of the most important sieges of the world history took place.


Due to its geographical position as a gate to the Aegean Sea, Rhodes has always had a vantage position on the trade routes between the West and the East and has been an important stop thanks to its well protected harbours. During the Hellenistic period in the late 4th century BC, the town of Rhodes was already enclosed in defensive walls which allowed to withstand the siege of Demetrius Poliorketes king of Macedonia, in 305 BC. The famous Colossus of Rhodes was built to thank gods for the victory against Demetrius.
Philo of Byzantium author of the treatise “Paraskeuastica” on defensive works, stayed in Rhodes in the 3rd century BC and expressed his admiration for its walls. The Rhodes earthquake of 226 BC severely damaged the fortifications, but they were soon rebuilt. The Byzantines built a fortress on the highest part of the town.

The milestone of the medieval history of Rhodes was its occupation by the Knights of the Order of St John of Jerusalem (or “Knight Hospitallers ” or just “Knights”) in 1309.

The Order was founded in Jerusalem after the 1st Crusade and officially recognized by the Pope in 1134. Initially, their mission was the medical care of the crusaders and the pilgrims, but gradually they gained military and financial power. After the loss of Jerusalem (1187) they withdrew in the County of Tripoli (the last Crusader state in north Lebanon) and after the fall of Acra in 1291, they sought refuge in Cyprus. From there they decided that Rhodes would be their next home and planned an invasion.

When the Knight Hospitallers arrived, the town was still wealthy but in decline. Rhodes underwent an economical growth thanks to the richness that the knights brought in from the Holy Land and to the inheritance of the Templar’s assets given to the Hospitallers after the Templar Order was suppressed in 1312 by decree of the king of France Philip IV. The richness of the island attracted the Ottomans from the nearby coast (Turkey is just 18 km away and can be easily seen from Rhodes). The knights started continuous works on the fortifications, both to include the new villages in the South of the historical Byzantine town and to update the fortification to the new military defensive techniques after the artillery started to be used currently as a siege means.

The Knights of Saint John had had a long experience in building fortresses and fortifications during the almost three centuries of their stay in the Holy Land, nevertheless the reference model for the construction of the fortification were the Theodosian Walls of Constantinople which, during the centuries, had shown a great capacity to withstand sieges.

The expansion of the walls was undertaken by Grand Master Antonio Fluvian de Riviere (1421-1437) who allowed the (medieval) town of Rhodes to reach the current area of about 42 hectares (104 acres). The wall curtain was finished between 1457 and 1465. The Byzantine fortifications were demolished leaving just a portion of those of the old fort known at the time of Knights as Collachium (Greek: Κολλάκιον).

In 1440 the Mameluke sultan of Egypt tried without success to conquer the town sieging it for 40 days.

In 1480 Rhodes was besieged by the troops of Mehmed II but the powerful army of the conqueror of Constantinople manned with 100,000 troops and 170 ships was repelled by the courage of the Knights and the strong fortifications, notwithstanding the outnumbering assailants.
In 1481 a destructive earthquake struck again the island causing severe damages to the houses and the fortification and about 30,000 casualties. A new Ottoman siege could not be withstood, so the Knights made available their great financial resources and in a very short time the most important palaces of the town and the fortifications were rebuilt. In the following years Grand Masters Pierre d'Aubusson, Emery d'Amboise, Fabrizio del Carretto and Philippe Villiers de l’Isle Adam ordered the fortifications to be rebuilt to withstand the cannons. For the purpose they called to Rhodes the best Italian military architects. Among them Matteo Gioeni, Basilio della Scuola, Gerolamo Bartolucci and Gabriele Tadino da Martinengo. The latter two were present in Rhodes during the final siege in 1522.

The Ottoman returned in 1522. The army of Sultan Suleiman the Magnificent besieged the city with 400 ships and 100,000-2000 men for six months. The city was defended by 7,000 armed men. In December 1522, the Grand Master Philippe Villiers de l’Isle Adam realized that the Christians could not hold much longer and decided to surrender. The few survivors and 4,000 of the Christian population were allowed to leave with 50 ships. They ended up in Malta after a few years.

The Ottomans repaired and maintained the walls but they did not add new elements in the fortification.

Structure, Fortification & Buildings

The gates of the old town of Rhodes

There are 11 gates to access the old city. Some of them are ancient, some are modern. The ancient gate of Saint George was closed by the Grand Master d'Aubusson after the siege of 1480 and transformed into a bastion. Starting from the Palace of the Grand Master that is from North-West towards the South they are:

Gate d’Amboise

The d’Amboise Gate (GreekΠύλη ντ’Αμπουάζ) is a grand gate just below the Palace of the Grand Master. It has a triple defensive belt with chemins de ronde, two round towers and covered entrance. Remains of the ancient studded wood doors are still visible. The most powerful bastion of the city, the Saint George bastion, pentagonal in shape, covered with its cannons the access through the gate.

Gate of Saint Athanasios

This gate was built between 1441 and 1442. It is also known to locals as Saint Francis Gate since the church of Saint Francis of Assisi, built by the Italians, is just outside the gate. The round tower of Saint Mary that controlled the entrance to the gate was built in 1441 by the Grand Master Jean de Lastic .
According to the Turkish tradition, the troops of the conqueror Suleiman the Magnificent entered Rhodes through this gate. The gate was closed by the sultan who wished to avoid that any other conqueror could pass after him. But most probably the door was closed by the Hospitallers for security reasons. It was re-opened by the Italians in 1922 during the 400th anniversary of the conquest of Rhodes by the Ottomans.

Gate of Saint John

The Gate of St John (Πύλη Αγίου Ιωάννου) is commonly known as Koshkinou or Porta Kokkini (Πόρτα Κόκκινη, "red door"). According to the tradition during the siege of 1522 there were so many fallen men in front of this gate that the stones were dyed red. The external fortification the Gate of Saint John was built by the Grand Master d'Aubusson to strengthen the fortifications built by his predecessors.
In 1912 the Italian troops entered the town through this gate. A frame which is currently empty, hosted a commemorative stone.

Acandia Gate

The Acandia Gate (Πύλη Ακαντιάς) was opened by the Italian administration in 1935 in the segment of fortifications to the North-East of the Del Carretto bastion to connect the commercial harbour with the South-East zone of the town beyond the medieval town. For the occasion a new street was outlined (via Del Carretto, nowadays Alhadeff Street) to connect Acandia Gate with the Gate of the Virgin.

Gate of Saint Catherine

The Gate of St Catherine (Πύλη της Αγίας Αικατερίνης) is also known as the Windmills Gate, since it allowed to reach the grain mills on the harbour mole from the commercial part of the town.

Gate of the Virgin

The Gate of the Virgin (Πύλη Παναγίας) is a modern gate, envisaged in the town master plan by the Italian administration to allow vehicle traffic, but opened only in 1955 by the Greek administration. Its name comes from the nearby church of the Virgin of the Burgh (or Virgin of Chora, meaning "main town"), The name "Burgh" comes from the bourgeois (as opposed to Knights) who inhabited this part of the town.

Marine Gate

The Marine or Sea Gate (Πύλη Θαλασσινή) was the main entrance to the town from the harbour. Its defensive towers have a representative task more than defence in facts due to the reduced space between the waterfront and the walls no army could have ever attempted an attack from this side of the fortifications. During World War II the Allied bombings destroyed the upper part of the North tower. In 1951 the gate was restored by the Greek administration together with the Gate of Saint Paul.

Arnaldo Gate

The Arnaldo Gate (Πύλη Αρνάλδου) is a small gate that gives access to the New Hospital of Saint John, which hosts currently the Archaeological Museum of Rhodes .

Gate of the Arsenal

The Gate (in Greek: Πύλη Ταρσανά) was built during the 14th century by the Grand Master Juan Fernandez de Heredia whose coat of arms stands on top of the gate. In 1908 the Ottoman administration demolished the side towers to widen the access road to the Kolona harbour. Today thanks to the direct connection with the Liberty gate it allows a fast flow of vehicles between the Kolona harbour and the new town.

Gate of Saint Paul

The Gate (in Greek: Πύλη Αγίου Παύλου) was built in the second half of the 15th century to allow the access to the fortified city and the Kolona harbour. The Gate of Saint Paul was almost completely demolished during World War II and was rebuilt together with Marine Gate in 1951.

Liberty Gate

The Liberty Gate (Πύλη Ελευθερίας) was opened by the Italians in 1924, who portrayed themselves as liberators from Ottoman rule. It is the main access to the Kolona harbour and allows the connection between the Kolona and Mandraki harbours. Although it is a modern gate it was built respecting the architectural style of the medieval gates. The road that crosses it continues through the Arsenal gate.

Bastions and towers

Bastion of Saint George

The archetype of European bastions in the new age of gunpowder arms. It has a pentagonal shape and represents one of the examples of a gate transformed into a bastion through subsequent modifications that took place until the final siege of 1522. With the addition of the powerful terreplein of Spain the Bastion of Saint Georges is the model of the successive modern forts all over Europe. Its final transformation was designed by the Italian architect Basilio della Scuola and carries coat of arms of the latest Grand master in Rhodes Philippe Villiers de l’Isle Adam.

Bastion of Italy

Post of Italy or Del Carretto Bastion. This is the place where the troops of Mehmed II breached the walls and were then repelled by the knights during the siege of 1481. Grand Master Fabrizio del Carretto had it armoured with a chemin de ronde to hold cannon emplacements.

Naillac Tower

An impressive tower that was the landmark of Rhodes in the past centuries. It was built between 1396 and 1421 by the Grand Master Philibert de Naillac before the development of the cannons on the mole east of the Gate of Saint Paul that closes the commercial harbour. It had a square shape like many other medieval towers and was 46 m high. It was the terminal of the wall belt facing the harbour and was used as a watch tower. It was severely damaged during the earthquakes of 19th century and was demolished by the Ottoman administration.

Windmills Tower

It is known as Tower of France or Tower of the Angel. It was one of the two towers protecting the Commercial habour ("emporium" in Greek Εμπόριον). It was built on the natural mole East of the harbour by the Grand Master d'Aubusson who had the coat of arms of France placed on the tower (hence one of its names). On the mole there were originally 13 windmills. Today only one is left.

Tower and Fort of Saint Nicholas

The Mandraki (in Greek Μανδράκι) was the military harbour and was guarded by a tower built between 1464 and 1467 by the Grand Master Zacosta at the end of the natural mole. After the siege of Rhodes in 1480 the Grand Master d'Aubusson added a bastion around the tower transforming it into a guard fortress on the sea. The tower has a seperate page in our site, Del Carretto .

Terreplein of Spain

This terreplein (embankment) was built in the middle of the moat together the other two after the siege of 1480. It avoided that the cannon could have a free range on the walls and in case of the assailants invading the moat could be reached through underground passages that could be blown rapidly in case of withdrawal. In 1522 the Ottoman tried to undermine the terrepleins by tunneling under the moat.
The terreplein of Spain is placed in the South West portion of the walls on the side of the Gate of Saint Athanasiou and was guarded by the knights of the langue of Spain.

Terreplein of England

Placed in the South side of the walls between the Gate of Saint Athanasiou and the Gate of St John was guarded by the knights of the langue of England

Terreplein of Italy

The terreplein of Italy was placed in the south East portion of the wall just North of the Bastion of Italy and guarded by the knights of the langue of Italy. It was partially demolished and split into three portions by the Italian administration, in the 1930s, to open the Acandia Gate.

The Medieval Town

Contained within the Fortifications of Rhodes is the largest active Medieval town in Europe, with over 6,000 inhabitants. The Medieval town, as well as being part of the UNESCO world heritage site, is also a major tourism attraction. The Medieval town (Παλαιά Πόλη) contains a number of sites, including the clock-tower, Socrates Square, the Jewish Square, the old Haman, Suleiman Mosque Socrates Street, the Street of the Knights, and the Palace of the Grand Master of the Knights of Rhodes.

The Medieval Town contains a number of different architectural styles, due to its history. The town mostly developed under the Knights of St John, which accounts for its predominantly Gothic architecture. However, after the second Siege of Rhodes the Medieval town was also developed in the Ottoman era. New buildings were constructed including: mosques, public baths and mansions for the new patrons.

Collateral stories

The architectural significance of Rhodes, is summarised by UNESCO when it states:
“...with its Frankish and Ottoman buildings the old town of Rhodes is an important ensemble of traditional human settlement, characterized by successive and complex phenomena of acculturation. Contact with the traditions of the Dodecanese changed the forms of Gothic architecture, and building after 1523 combined vernacular forms resulting from the meeting of two worlds with decorative elements of Ottoman origin. All the built-up elements dating before 1912 have become vulnerable because of the evolution in living conditions and they must be protected as much as the great religious, civil and military monuments, the churches, monasteries, mosques, baths, palaces, forts, gates and ramparts.”
