The 1689 Brașov fire took place in the town of Brassó in the Principality of Transylvania (now Brașov, in Romania; German Kronstadt). It broke out on the afternoon of 21 April in the lower (i.e. southwestern) parts of Burggasse and Schwarzgasse streets (today Str. Castelului and Str. Nicolae Bălcescu). Spread by a powerful wind, it soon engulfed the entire part of the town facing the Tâmpa mountain. Local fires also appeared in Roßmarkt (today Str. George Barițiu) and Purzengasse (today Str. Republicii). Within a few hours, the entire town was in flames. The White Tower, the Black Tower, the Council House and the Black Church were all damaged. Church services were held outdoors for a long time. Johannes Honter's renowned library also perished.
