Valhallavägen forms the northeast boundary of the city centre, running north of Östermalm from the 1912 Olympic Stadium to Ladugårdsgärdet. It was built as part of the regeneration of Östermalm from slum dockland to the plush part of the city it remains to this day.
The stadium is far smaller than we expect these days - these days they need to support a whole village of TV crews and technologists as well as the athletes.
The avenue itself is a broad, treed road with traffic along each side and paths and parking in the centre, under the trees.
Ladugårdsgärdet is a large area of parkland, more like Hampstead Heath than, say, Hyde Park, it connects with Djurgården, home of Skansen and Gronalund.
