The Basilica Cistern around closing time, Istanbul, Turkey on 10th May 2023 – by Ed Coulson

“More than 300 marble columns create a space that could hold 80,000 cubic metres of water. 

The space hums with constant reverberations from the slightest sounds. 

I stood at the very back corner of the cistern and recorded while the last few visitors made their way round the rattling gangways.”
