Skopje fire of 1689
The fire of Skopje started on 26 October 1689 and lasted for two days, burning much of the city; only some stone-built structures, such as the fortress and some churches and mosques, were relatively undamaged. The fire had a disastrous effect on the city: its population declined from around 60,000 to around 10,000, and it lost its regional importance as a trading centre.
