SS Mariefred

The SS Mariefred is a steamship and floating working museum on Lake Mälaren, carrying passengers between Stockholm and Mariefred. The vessel displays a traditional steam engine, smokestack, and simple wooden deck that clearly reveal its age and early 20th-century origins.

The ship was built in 1903 and has continuously operated on Lake Mälaren since then. It represents the development of steamship travel in Sweden and was designated a protected historical monument.

The vessel takes its name from the town of Mariefred, its destination on Lake Mälaren. Visitors can observe how early passenger travel was organized and what role steamships played in connecting communities.

The ship operates regular routes from Stockholm to Mariefred during the season, with each journey taking about two hours. Visitors should prepare for rough water, especially in windy conditions, and bring warm clothing as it gets cool on deck.

The ship still uses its original 1903 engine and runs on coal, making it one of the few remaining coal-powered passenger vessels actively operating. Visitors can watch real steam power being generated as the stoker works before their eyes.
