The Underground Bath is a historic hammam on Boyuk Gala Street in Icherisheher (the Old City) of Baku, Azerbaijan, situated near the ancient fortress gates of one of the Caspian world's most remarkable medieval urban enclaves. Baku's Old City, a UNESCO World Heritage Site, preserves a dense concentration of medieval defensive walls, caravanserais, mosques, and hammams, with the celebrated Shirvanshah's Palace hammam among the most famous. This underground bath, integrated into the basalt rock beneath the old city's tightly packed fabric, reflects the ingenuity of Azerbaijani bath builders in exploiting both the thermal properties of the Absheron Peninsula's geologically active subsoil and the natural insulating qualities of underground construction.

Insider tip — The Underground Bath in Baku's Icheri Sheher (Inner City) is a UNESCO World Heritage site — an extraordinary subterranean hammam excavated from the ancient rock of the walled old city, part of the dense medieval Islamic architecture predating the oil era by centuries. The Icheri Sheher's underground hammam reflects the architectural sophistication of Shirvanshah-era Baku when the city was the capital of a prosperous medieval Azerbaijani kingdom on the Caspian trading routes, before petroleum transformed every dimension of its identity.
