Sabayil Castle.

Introduction: The Submerged Marvel of Baku

Sabayil Castle, often referred to as the “Atlantis of the Caspian Sea,” stands as one of Azerbaijan’s most captivating and mysterious medieval sites. Situated off the southern coast of Baku near the Bayil district, this partially submerged fortress was constructed between 1232 and 1236 CE under Shirvanshah Fariburz III. Designed to defend the Absheron Peninsula and serve as a royal residence, Sabayil Castle’s unique maritime setting and architectural sophistication offer a remarkable window into Azerbaijan’s layered history—a blend of Persian, Arabic, and Islamic influences (Azerbaijan National Academy of Sciences, Azernews, 7 Day Adventurer).

The castle’s polygonal structure, robust walls with 15 towers, and ornately inscribed stone slabs exemplify the advanced engineering and artistry of the Shirvanshah era. After a devastating earthquake in 1306 submerged the fortress, Sabayil Castle became a natural time capsule—preserving artifacts and carvings now displayed in Baku’s museums and exhibitions. Today, visitors can explore its legacy through guided boat tours, museum exhibits, and panoramic coastal views.

This guide provides a detailed overview of Sabayil Castle’s history, architecture, visitor experience, ticketing, accessibility, and travel tips, helping you plan an unforgettable journey into Azerbaijan’s rich medieval heritage.

Discovering Sabayil Castle

Sabayil Castle lies approximately 350 meters off Baku’s southern coastline in the Caspian Sea, its remains emerging or submerging with changing water levels. The fortress’s dramatic history and enigmatic setting have earned it the nickname “Caspian Atlantis,” attracting both scholars and adventure seekers interested in Azerbaijan’s medieval legacy.

History and Architecture

Origins and Construction

Sabayil Castle was built between 1232 and 1236 CE by order of Shirvanshah Fariburz III and designed by Zejnaddin ibn Abu Rashid Shirvani (Azerbaijan National Academy of Sciences). Its island location and advanced defensive features—thick limestone walls, 15 towers, and a narrow, controlled entrance—underscored its strategic role in protecting Baku from maritime threats while serving administrative and customs purposes.

Architectural Features

The elongated, trapezoidal layout measured about 180 by 40 meters, with walls up to 2 meters thick. Three round and twelve semicircular towers strengthened the fortress, while a now-lost platform on the western side is believed to have supported a central observation tower. Inside, archaeological research has revealed foundations of at least nine structures—likely barracks, storage, administrative offices, and possibly a fire-worshipper temple hinting at Zoroastrian influences.

Decorative Elements and Inscriptions

A defining feature of Sabayil Castle is its frieze of over 700 inscribed stone panels. Spanning more than 400 meters, these slabs bear Arabic and Persian inscriptions, geometric motifs, and reliefs of human and mythical figures. They include the names of 15 Shirvanshahs, providing invaluable historical context (Azernews).

Submersion and Preservation

In 1306, an earthquake caused the islet and castle to sink, preserving the lower structures and inscriptions while upper levels collapsed. Over subsequent centuries, fluctuating Caspian Sea levels periodically revealed parts of the fortress. The 18th and 20th centuries saw major archaeological efforts to recover and study inscribed stones, many of which are now housed in Baku museums.

Archaeological Discoveries and Tunnels

Modern excavations have uncovered a network of underground tunnels connecting Sabayil Castle to Baku’s Old City, including the Shirvanshahs’ Palace and Synykh Gala mosque. While some passages date to the 19th century, they reveal the sophistication of medieval Baku’s defensive and administrative infrastructure (7 Day Adventurer).
