Mysterious, shrouded in legends and tales Sabayil castle is of particular interest because it is located directly under the water, 350 meters from the shore, and often for this reason is called the Atlantis of the Caspian Sea. It was constructed on a rocky island in the Baylovskoy Bay by Shirvanshah Fariburz III, in 1235. In 1306, the fortress went into the water because of the strong earthquake in the south of the Caspian Sea and the dramatic rise of the sea level. It was only in the early 18th century, when the Caspian Sea retreated, that the island resurfaced.
