Local officials dispatched firefighters, ambulances and police units to Sütlüce’s İmrahor Avenue as amazed locals watched on as a four-storey building stood on a cliff without its foundation.
The road was closed to both pedestrians and car traffic as a precaution.
The building eventually collapsed at 12:10 p.m, causing no casualties.
The building’s owner Emin Ertürk said they had warned authorities about the constructionof a hotel in the adjacent plot, which he said was financed by former Barcelona footballer Arda Turan.
On the other hand, Beyoğlu Mayor Ahmet Misbah Demircan said the collapsed apartment, which was built in 1994, did not have required permits.
