The mosque is nicely situated at the waters edge. Official name Büyük Mecidiye Camii. Büyük Camii means Big Mosque, and was built on orders of Sultan Mecid I, hence Mecidiye (I first thought it was named after a certain coin, but was put right, thanks to the comment below). The building is from 1854, needs some repair. The high rise in the back is of a more recent date.
