Election results

Twin towns — sister cities

In 1942, Lidingö created a committee to provide support for the people in Lohja (Swedish: Lojo) in the southern part of Finland who suffered badly during World War II. An orphanage was opened in Lidingö and money was collected and sent to Lohja. The orphanage was closed in 1943 as most of the children then had returned to Finland. The money that was left over was used to provide food for the children in Lohja. Lidingö and Lohja still maintain a close relationship.

Another sister city is Alameda, California. The initiative came from Alameda in 1959 and was part of U.S. President Dwight D. Eisenhower's people-to-people-movement. The purpose was to develop better understanding between people from different countries after World War II. Both Alameda and Lidingö are islands with a bridge connecting them to a big city.

As the Baltic countries were liberated from the Soviet Union in 1990-1991, Lidingö looked for a new sister city in the area. Saldus in Latvia was selected. During the years, a number of environmental, cultural and other projects have been accomplished.
