Nacka Municipality (Swedish: Nacka kommun) is a municipality in Stockholm County in east-central Sweden. Its seat is located at Nacka. The municipality is situated just east of the Swedish capital, Stockholm, and its western parts are considered a suburban part of the city of Stockholm.
The present municipality was created in 1971 when the City of Nacka (itself instituted in 1949) was amalgamated with Saltsjöbaden (itself detached from "old" Nacka in 1909) and Boo.
Slussen is a station on the Stockholm metro and Saltsjöbanan, located at Slussen in the district of Södermalm. The metro station is served by the Red and Green lines, and originally opened in 1933 as an underground tram stop, on 1 October 1950 it became the terminal of the first metro line running south to Hökarängen, it was again rebuilt when the extension of the line north to Hötorget was opened on 24 November 1957. On 5 April 1964, the first stretch of the Red line, between T-Centralen and Fruängen, was opened.
Slussen has also been the terminus for the Saltsjöbanan railway since the 1940s, however this has temporarily been moved to Henriksdal in 2016 due to the reconstruction of Slussen. Traffic will resume when the reconstruction is complete due in 2028. Just outside the northern entrance to the metro station, there is a bus terminal for buses to the Nacka and Värmdö municipalities.
Värmdö is an island in the innermost region of the Stockholm archipelago and covers an area of 181.40 km, making it the largest island in the archipelago. Värmdö is after Gotland and Öland the third largest island on the eastern coast of Sweden.
Värmdö lies in Stockholm County. Most of it forms part of Värmdö Municipality along with other islands, but the western end is part of Nacka Municipality, which lies mostly on the mainland, to which Värmdö is connected by a road bridge.
