I NEEDED NEW shoes today (20th April 2024). After buying a pair in the superbly stocked Fast Step shoe shop, we felt the need for coffee. Near the shop, we found a café called Gutta. Having enjoyed good coffees – both Turkish style and Italian style, we needed to answer the call of nature.

We asked if the café had a toilet. It did not, but, as has happened frequently in Istanbul, we were directed to the nearest mosque. This mosque, like others in Istanbul, has public toilets, for which in this case a modest charge was levied. As with most WCs in Istanbul, this one was well-maintained.

The mosque in this case is called the Kalenderhane Mosque. Its name derives from the Kalender dervishes, who once used it as a ‘tekke’. From the outside it looks remarkably like a very old Greek Orthodox church. It was converted for the use of the dervishes by Sultan Mehmet (the Conqueror) in 1453. In the 18th century, it was converted into a mosque.

Built in about the 9th to 10th century next to the Aqueduct of Valens , it is now thought to have been dedicated to Theotikos Kyriotissa. Sadly, as it was locked up, we were unable to enter the edifice.

Had it not been for nature’s call, we might not have come across this interesting mosque. As is the case for many old mosques in Istanbul, it is a fine example of Ottoman repurposing existing Christian buildings in the 15th century.
