Incorporated in 1943, Solna's history stretches much further back. The parish of Solna was formed sometime in the 12th century, and the current boundary with the City of Stockholm was established as early as 1670. In the late 1800s new areas of Solna were settled as suburbs of Stockholm, and the first tram line reached Solna in 1908. The last of these was closed in 1959, though in 1975 the city got its first subway stations. There are now plans for a light rail line to go to Solna. Today more people commute to Solna than from it; in fact it has a net commuting surplus of 26,100.
The top international events in Solna's history are the 1958 World Cup (won by Brazil) and the 1992 UEFA European Championships (won by Denmark).
