Baku’s medieval core is a UNESCO-protected site surrounded by 12th-century walls, brimming with history and Eastern architecture. Here you’ll find the Maiden Tower, Baku’s most mysterious site – no one knows for certain what it was originally built for! Meanwhile, occupying the highest spot in the citadel, the Shirvanshahs’ Palace was the 15th-century residence of Azerbaijan’s medieval rulers. Beyond its main attractions, the ‘Inner City,’ as it’s called by the locals, is a labyrinth of narrow alleyways home to some of Baku’s oldest residents, as well as artists’ workshops, souvenir stalls and traditional restaurants serving classic Azerbaijani dishes.
