A cistern-like Byzantine-era structure has been unearthed during renovation of an underpass in Istanbul’s Beyazıt neighborhood. The construction company had tried to cover up the entrance to the structure to continue its work, but thanks to the keen eyes of a local citizen it has been rescued from being buried underground, according to daily Hürriyet. 

The Istanbul Metropolitan Municipality initiated a tender for renovation work on the Darülfünün underpass in August. The tender was won by an Işıldak Construction and Mak. İş. Construction consortium, and the renovation began after the project was approved by the Istanbul Preservation Board No: 4. 

During work by subcontractor Vizyon, the covers of two tombs in the area were found in August. The tomb covers, estimated to date back to the early Christian era, were badly damaged by a digger. After the covers were taken to the Istanbul Archaeology Museum, the museum became aware that it had not been informed about construction work in the area, but work nevertheless restarted a short time later.
