The double castle gate is one of the main entrances to the Old City of Baku, which is surrounded by castle walls 8-10 meters high and 3-3.5 meters wide. This gate is considered a masterpiece in the world of architecture, as it is a huge fortress with stones of varying sizes that suggest prestige and grandeur. Today, the gate and the surrounding area are one of the most important tourist facilities in the city, with restaurants, cafes and open squares spread around it.
