Bilge Castle

Bilge Fortress is a historical structure built of white stone in the 13th-14th centuries in the village of Bilge in Baku. This fortress was created by the Shirvanshahs as a defensive and observation structure. Currently, only a part of the fortress has survived to this day. It was used for a long time as a lighthouse to help ships find the shore at night and avoid shipwrecks. Therefore, the fortress is also known as the "bonfire tower".
