Ropsten is a cape at the eastern point of the Stockholm mainland at the inner part of the Stockholm archipelago, in Sweden. Two bridges named Lidingöbron extend from Ropsten over to the island of Lidingö. The Ropsten area is located between Hjorthagen and the Stockholm city main port, Värtahamnen. Ropsten is the terminal station for the eastern part of Stockholm Metro system and is also the terminal station for Lidingöbanan, the railway for public transportation covering the area of Lidingö.
