The Amir Ahmad historical bathhouse (also known as Hammam-e Sultan Amir Ahmad) is an old Persian public bathhouse built in the 16th century, named after Imamzadeh Sultan Amir Ahmad. After being damaged in an earthquake in 1778, the bathhouse was restored in the Qajar era. The bathhouse has a total area of 1000 sqm and consists of several rooms interconnected by corridors. The interior of the bathhouse is richly decorated with turquoise and white tilework. Several domes with circular glass windows let light into the rooms.
