A fierce fire engulfed an old boat house at Finnberget in Nacka, south of Stockholm, late Monday night.

The blaze, reported around 11 PM, quickly consumed the entire structure.

Seven fire units battled the flames, focusing on preventing the fire from spreading to nearby boats in the harbor.

Despite their efforts, the boat house burned down completely by 2:30 AM Tuesday.

No injuries were reported.

The cause of the fire remains unknown, and police have initiated an investigation for possible public endangerment.

The incident highlights the challenges of fire control in marina areas and the quick response of local emergency services.
