Dört Dönem Katmanlı Yapı

Tucked behind a mundane open-air parking lot on Alayköşkü Street lies one of Istanbul's most quietly remarkable architectural sites: a structure whose rear facade reads like a compressed timeline of the city's history. Visible strata span Byzantine medieval masonry, Ottoman construction phases, and early Republican-era additions from the twentieth century. The widely repeated claim of a fourth, classical Roman layer is disputed by researchers — the oldest identifiable phase appears to be Byzantine rather than ancient Roman. There is no signage, no ticket booth, and no formal museum setup; access is granted simply by nodding to the parking lot attendant. The reward is a rare, unmediated encounter with Istanbul's layered identity, stacked in stone and mortar for anyone willing to walk around the back.
