[3] According to legend, Lidingö was a place where the Vikings would gather before setting sails to eastern areas, however no proof have been found to confirm that theory.

When the city arms was to be chosen in 1928 a Viking ship became the motif, in the colors of the Swedish flag.

Lidingö was first mentioned in writing in 1328, called Lydhingö when the entire island and the farms were owned by Bo Johnsson Grip.

Much of the populated land area is built with one-family houses; a total of 36% of the population, or 17,020 people (2006), live in such houses [1] and, to a large extent, commute to work in Stockholm or other municipalities of Greater Stockholm.

Lidingö is one of the wealthiest municipalities in Sweden, with the fourth highest median income per capita.

Chairman of the municipal executive board is Anna Rheyneuclaudes Kihlman from the Moderate Party.

Millesgården is an art museum and sculpture garden, located on the island of Lidingö, created by Carl and his wife Olga Milles.

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.

The purpose was to develop better understanding between people from different countries after World War II.

As the Baltic countries were liberated from the Soviet Union in 1990-1991, Lidingö looked for a new sister city in the area.
