Bodrum Castle and Maritime Museum: Underwater Treasures
Introduction: Where Medieval Knights Meet Ancient Mariners
Rising majestically from the azure waters of Bodrum's harbor, the Castle of St. Peter (Bodrum Castle) stands as one of the world's most remarkable examples of medieval military architecture transformed into a cutting-edge archaeological institution. This 15th-century Crusader fortress, built by the Knights Hospitaller, now houses the Bodrum Museum of Underwater Archaeology—the world's largest museum dedicated to underwater archaeological discoveries.
The castle's transformation from a medieval stronghold to a premier archaeological center represents a unique fusion of crusader heritage and maritime archaeology. Within its ancient walls lie treasures spanning over 4,000 years of seafaring history, making it a pilgrimage site for both history enthusiasts and maritime archaeology lovers.
Historical Foundation: The Knights' Legacy (1402-1523)
The Crusader Vision
In 1402, as the Ottoman Empire consolidated its power across Anatolia, the Knights Hospitaller recognized the strategic necessity of establishing a mainland stronghold. Grand Master Philibert de Naillac (1396-1421) identified the perfect location: the ancient site of Halicarnassus, where the ruins of one of the Seven Wonders of the Ancient World provided ready-made building materials.
Construction Chronicles
**Phase 1: Foundation (1402-1437)**
The castle's construction began in 1404 under the supervision of German knight-architect Heinrich Schlegelholt. In an extraordinary historical irony, the builders systematically dismantled the Mausoleum at Halicarnassus—the tomb that gave the world the word "mausoleum"—to construct their fortress. Squared green volcanic stones, marble columns, and relief sculptures from the ancient monument were incorporated into the castle walls.
**Papal Endorsement**
Pope Boniface IX granted a papal decree in 1409, guaranteeing construction workers "a reservation in heaven" for their sacred labor. This spiritual incentive drew craftsmen and laborers from across Christian Europe, creating a truly international construction project.
**Architectural Innovation**
The castle incorporated the latest military engineering concepts of the 15th century:
- Seven gates with twisted approach passages to confuse attackers
- Fourteen underground cisterns for water storage
- Strategic placement of 249 coats of arms and heraldic reliefs
- Four national towers representing different European powers
The National Towers: A European Alliance in Stone
**English Tower (Completed 1413)**
The three-story English Tower, also known as the "Lion Tower" for its carved lion relief, displays the coat of arms of King Henry IV of England. Accessible only by drawbridge, it served as a last-resort stronghold and now houses Ottoman maritime artifacts.
**French Tower**
Built in distinctive French Gothic style, this tower reflects the sophisticated architectural traditions of medieval France and contains exhibits of medieval weaponry and naval equipment.
**German Tower**
Designed by the German architect Heinrich Schlegelholt, this tower showcases Germanic engineering excellence and houses collections of ancient coins and jewelry.
**Italian Tower**
The Italian Tower, reflecting Renaissance architectural influences, now serves as the Coin and Jewelry Hall, featuring one of the world's finest collections of ancient Mediterranean artifacts.
Strategic Importance and Decline
For over a century, St. Peter's Castle served as the second most important Hospitaller stronghold, providing refuge for Christians throughout Asia Minor. The castle successfully withstood Ottoman attacks in 1453 and 1480, but ultimately fell to Sultan Suleiman the Magnificent in 1523 during his conquest of Rhodes.
**Ottoman Transformation**
Following the Ottoman conquest, the castle chapel was converted into the Süleymaniye Mosque, with a minaret added in 1671. The fortress continued to serve various functions under Ottoman rule:
- Military garrison during the Greek War of Independence (1824)
- Public bath (hamam) installation in the 19th century
- Prison facility (1895-1921)
- Italian garrison post (1918-1921)
The Archaeological Renaissance: Birth of a World-Class Museum (1960s)
Visionary Transformation
After standing empty for four decades following World War I, Bodrum Castle found new purpose in 1962 when the Turkish government recognized its potential as a unique archaeological venue. The decision to establish the Bodrum Museum of Underwater Archaeology marked the beginning of a revolutionary chapter in maritime archaeology.
Pioneering Partnership
The transformation was catalyzed by groundbreaking underwater excavations conducted by the Institute of Nautical Archaeology (INA) beginning in 1960. These excavations represented the dawn of scientific underwater archaeology in Turkey and the Eastern Mediterranean.
