June 2017 - Chania
Between the Venetian and Old harbours of Chania sits the mosque of the Janissaries, built in 1645 after the Turks captured the town. It is the oldest Ottoman building in Crete, now used for various exhibitions. Despite the minaret being destroyed in WWII, the rest of the mosque is surprisingly stable, including the stunning blue and white mihrab.
(I tried to get a decent picture of the latter but there were too many people!)
