Zeyrek Çinili Hammam (Zeyrek Tiled Bathhouse) is one of Istanbul’s most remarkable Ottoman-era hammams, located in the historic Zeyrek district, near the Aqueduct of Valens. Built in the 16th century by Mimar Sinan, this double-bath structure was designed to serve both men and women separately. The name "Çinili" (Tiled) comes from the exquisite Iznik tiles that once adorned its interior, though many have been lost over time. After years of neglect, the hammam underwent a meticulous restoration, reopening as a cultural site that preserves its original domes, marble interiors, and historical bathing traditions. Today, it stands as a hidden gem of Ottoman architecture, offering visitors a glimpse into Istanbul’s historic bathhouse culture.
