The City Hall doesn’t only boast an impressive history (after all, it is the place where the Nobel Prize banquet is held each year); its exterior can also be a quiet place to wind down after some major sightseeing.
You can find the City Hall just a few minutes walk from the central station and once you enter the portal you can either go to the City Hall to the right or cross the Italian-style piazza and walk straight ahead to the small park in front of the water. Considering how central this place is, and how absolutely beautiful it is, it is surprisingly quiet most days. I find it a very nice place to sit down and read a book or just sit quietly and admire all the ships passing by and the large island of Södermalm on the opposite side.
Entering the park is free of charge. If you want to climb the tower to get a view of the city, it is 60 SEK for people over 11 years old. A visit to the City Hall itself costs 120 SEK (including guide, which is mandatory for all visits) for adults during high season. Less during low season and for youth and children.
