Stadshuset is one of Swedens most famous buildings, designed in 1907 by architect Ragnar Östberg, who was very inspired by italian renaissance architecture at the time. Next to it is the newly finished Stockholm Water Front building.
A 500-meter long (quarter mile) walking path with a magnificent view of Lake Mälaren, City Hall, and Riddarholmen. Bring your take-away coffee and walk the path at least once every season to notice the different scents and colours of Stockholm.
In the summer this is a haven in the middle of the city. It is a public garden where I like to go and relax in the grass under a blooming tree. There is also a cafe and a shop here. Before you leave you should buy a bouqee of flowers (you pick yourself in the garden!).
