The State Fire and Rescue Service (VUGD) responded to a call at 11:30. Luckily they have a depot just on the other side of the Stone Bridge across the River Daugava and were on the scene within seconds.
After a brief battle with the flames at a corner section of the building, the fire crews were in control and began pulling off sheets of metal cladding and scraping out singed insulation materials as tourists arriving for a weekend Spring break looked on.
VUGD said a 15-square meter section of the roof was affected.
The cause has yet to be established.
