You might be biking along the Mälardalsleden trail through the varied and fertile landscape of Sörmland, with its deciduous trees and farms, enjoying the proximity to the water. About 12 kilometers north of Eskilstuna, there’s a real gem if you’re planning to stay a night or two. On a headland along the shore of Lake Mälaren lies Sundbyholms slott. The main building was completed in 1648 and was constructed at the initiative of Admiral Carl Carlsson Gyllenhielm. Today, it is a modern hotel and conference center with a fine restaurant and hotel rooms located in various buildings on the castle grounds.

Sundbyholm has all the prerequisites for relaxing and filling the time with experiences. A walk in the castle's surroundings gives many beautiful views, you can go down and look at the guest harbor or go down to the sandy beach and swim. Another attraction that is within cycling and walking distance is the famous Sigurd carving. The carving is from the 11th century and is made on a rock. It illustrates episodes from the Icelandic saga of Sigurd Fafnesbane. In short, the carving is well worth a visit.

Another thing worth knowing about Sundbyholm is that this is where Prince Eugen spent a summer in 1893 and painted his rightly famous oil painting ”The old castle".


The entire castle serves as a restaurant, banquet hall, and breakfast room. There are no guest rooms in the castle building itself. In the evenings, the castle serves a variety of dinner menus on white tablecloths by candlelight, and in the morning, a large breakfast buffet is served to overnight guests. In total, there are 109 hotel rooms with 233 beds at Sundbyholms slott. There are small double rooms, standard double rooms, junior suites, and luxury suites. The standard double rooms are located both in smaller buildings and in a large brick building from the 1960s, where the rooms have been renovated with beautiful fabrics, comfortable beds, and fully tiled bathrooms. Sundbyholm is also Nordic Swan-certified, demonstrating its commitment to environmental sustainability.
