Palace of the Grand Master of the Knights of Rhodes

The Palace of the Grand Master of the Knights of Rhodes is a prominent medieval castle located in the city of Rhodes on the Greek island of the same name. Originally constructed as a Byzantine citadel in the seventh century, the site holds deep historical roots, with recent studies suggesting it stands on the foundations of an ancient temple dedicated to the sun god Helios, possibly near the location of the famous Colossus of Rhodes. In 1309, the Knights Hospitaller occupied the island and transformed the existing fortress into their administrative headquarters and official residence. This conversion established the structure as a rare and significant example of Gothic architecture within Greece, serving as the seat of power for the Order's Grand Master.

The palace has witnessed pivotal moments in history, including the Great Earthquake of 1481 and two major sieges by Ottoman forces in 1480 and 1522. Following centuries of decline and damage, the building underwent extensive restoration between 1937 and 1940 under Italian architect Vittorio Mesturino during the period of Italian rule. Today, the palace remains intact and is owned by the Government of Greece. It functions as a museum open to the public, allowing visitors to explore its rich interior and learn about the era of the Knights. The site is also a key component of the Medieval Old Town of Rhodes, which was designated a UNESCO World Heritage Site in 1988 for its cultural significance and well-preserved fortifications.
