Don't know if or when it's open but there are some tables available outside. It's also right next to the entrance to Åsbyåsens nature reserve and across the street from some goats.

Nice place in the old part of Strängnäs. A yard for sitting outside, lot's of "fika" options and ice cream and plenty of space to rest your bike. Guided tours are also available if one is interested in the history of the buildings.

Very impressive. The visit was worthwhile. The existence of the palace theater was particularly surprising.

The castle is ideal for a short break; the large parking lot is free and you can even get a snack.

It is impressive how well the foundry art for these cannons was in the 17th century.
