Later that evening, the fire reached Sankt Peders Stræde, where the Valkendorfs Kollegium dormitory (lot "Nørre Kvarter 122") was engulfed in flames.
[9] Presumably simultaneously, the fire also reached Professor Hans Steenbuch's room on Studiestræde (lot "Nørre Kvarter 60").

The building housing the wine cellar known as "Blasen" on the corner of Vestergade and Nørregade was to be the first demolition, but this dangerous undertaking failed when the gunpowder blew up while men were still carrying in the charges.
[15] At Nytorv, the flames consumed Det Kongelige Vajsenhus (The Royal Orphanage) (now the location of the Copenhagen District Court).
[16] From Gammeltorv the inferno made its way down Klædeboderne, Skindergade, Skoubogade and Vimmelskaftet, heading towards Amagertorv, while from Nytorv the fire found fuel on Rådhusstræde towards Frederiksholms Canal and Slotsholmen.
New fires were reported: Count Adam Christoffer Knuth's house in Pustervig, a cellar in Købmagergade (Market Street) and a haystack at Nørreport (Northern Gate) all broke out in flames; the latter likely ignited by embers carried by the wind.

At the end of Snaregade was the house (lot "Snarens Kvarter 2") of the vice mayor, Christian Berregaard, which the people tried to save.
The gunpowder went off, people had to run for their lives and the vice mayor's house was set afire and burned to the ground.

Property losses from the fire can be accounted for with relative certainty as detailed surveys were made immediately afterwards.
