The Palace of the Grand Master of the Knights of Rhodes rises above the Medieval City as one of the island’s most commanding and historically significant monuments. Built by the Knights of St. John in the 14th century and later reconstructed during the Italian period, the palace reflects centuries of political power, military strategy, and architectural ambition. Today, it stands as a central landmark of Rhodes, offering visitors a compelling journey through the island’s medieval and early modern past.
Introduction
Dominating the highest point of Rhodes’ Medieval City, the Palace of the Grand Master of the Knights of Rhodes stands as one of the most imposing and historically layered monuments in Greece. Located in the northwestern part of the fortified Old Town, the palace is not only the most significant remnant of the Knights’ rule but also a defining landmark of Rhodes itself. Known locally as the “Kastello,” this monumental structure reflects centuries of transformation, from Byzantine stronghold to medieval administrative center, from Ottoman neglect to Italian reconstruction, and finally to a modern museum welcoming visitors from around the world.
Historical Background
The Palace of the Grand Master was originally constructed in the early 14th century, shortly after the Knights of the Order of St. John of Jerusalem took control of Rhodes in 1309. It was built on the site of an earlier Byzantine acropolis, which had existed at least since the 7th century AD. In antiquity, this area formed part of the lower acropolis of ancient Rhodes.
For more than two centuries, until the Ottoman conquest in 1522, the palace served as the administrative center of the Knights and the official residence of the Grand Master. Following the Ottoman takeover, the building—already damaged during the siege—was used as a barracks and later as a prison. Over time, it fell into severe disrepair. In 1856, a major explosion, caused by ignited gunpowder stored in the nearby Church of St. John, further devastated what remained of the structure.
When Rhodes passed to Italian control in 1912, the new administration undertook an ambitious reconstruction program. Between 1937 and 1940, under the supervision of Italian Governor Cesare Maria De Vecchi, the palace was rebuilt almost entirely. Although the Italians aimed to respect the medieval character, much of what stands today reflects 20th-century reconstruction rather than an untouched medieval original.
Architecture & Design
The palace is a rectangular structure measuring approximately 80 by 75 meters, organized around a large central courtyard of about 50 by 40 meters. The main entrance is located on the southern side and is flanked by two imposing medieval-style towers with battlements, creating an unmistakably fortified façade.
Inside, the spacious courtyard is decorated with statues from the Hellenistic and Roman periods. During the era of the Knights, the ground floor housed auxiliary functions such as kitchens, storage rooms, and stables. The upper floor contained the private apartments of the Grand Master, ceremonial halls, the Council Chamber, banquet rooms, and administrative offices.
Adjacent to the palace on its northwestern side stands the powerful Bastion of the Palace of the Grand Master, a solid artillery platform rising approximately 15 meters above the moat. Its cannons once protected not only the palace but also the northern and northwestern sections of the city and the Mandraki harbor. Until the late 15th century, it was the strongest defensive point of medieval Rhodes.
Notably, some of the cylindrical gate towers associated with the palace and nearby entrances were already considered outdated in fortification design at the time of their construction. While visually impressive and evocative of Western medieval architecture, they played only a limited defensive role during the major sieges of 1480 and 1522.
The Knights of St. John and Their Legacy
The Knights of St. John, also known as the Hospitallers, transformed Rhodes into one of the most formidable fortified cities in the Mediterranean. From 1309 to 1522, they developed an advanced defensive system and established a highly organized administrative state.
The Palace of the Grand Master symbolized both political authority and spiritual leadership. It was the seat of governance and the residence of the Order’s highest official. The structure represented not only military power but also diplomatic and administrative organization within the broader Christian world of the late medieval period.
The Knights’ legacy remains embedded in the layout of the Medieval City, and the palace is the clearest architectural expression of their presence on the island.

The Palace During the Italian Occupation
The Italian reconstruction between 1937 and 1940 dramatically reshaped the palace’s present appearance. Because the building had been largely reduced to ruins, the restoration relied heavily on available interior plans and historical interpretation. The result was a striking and monumental structure, though not an entirely authentic medieval reconstruction.
During this period, the palace functioned as the administrative headquarters of the Italian authorities and as the residence of the governor. The interiors were decorated with carefully selected medieval-style furnishings, antique pieces, mirrors, paintings, candelabra, and architectural elements. The Italians also transferred significant mosaic floors—primarily from secular and ecclesiastical buildings in Kos—installing them throughout the palace halls. These mosaics, dating mainly to the late Hellenistic period, remain among the most impressive features of the monument today.
After the Dodecanese were incorporated into Greece in 1948, the palace’s upper floor was converted into a museum, and the monument evolved into one of Rhodes’ principal cultural attractions.
What Visitors Can See Today
Today, the Palace of the Grand Master hosts permanent exhibitions focusing on the ancient and medieval city of Rhodes. On the ground floor, a major exhibition titled “Rhodes from the Early Christian Period until the Ottoman Conquest (1522)” presents archaeological finds from excavations in the Medieval City.
The exhibition, established in 1993, is organized thematically into sections including Economy, Daily Life, Defense and Administration, Spiritual Life, Worship and Art, and Architecture. Displays include sculptures such as capitals and sarcophagi, ceramics, glass objects, portable icons, detached wall paintings, coins, and lead seals. Introductory texts and visual panels help contextualize the historical development of the city from the 4th century AD to the beginning of Ottoman rule.
On the upper floor, visitors encounter the reconstructed ceremonial halls and rooms adorned with Hellenistic mosaics and period furnishings installed during the Italian era. The experience emphasizes scale, symmetry, and architectural atmosphere, offering a self-paced visit through stone corridors, fortified features, and expansive chambers.
Visit duration varies. A brief walkthrough may take 45 minutes, while a standard visit typically lasts 60 to 90 minutes. Those who explore the exhibitions in detail may spend up to two hours inside.
