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!).
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.
