Great historic fort - always worth a visit!

Open on selected dates until grand opening August 24.

Go on a fantastic trip through the harbour of Copenhagen and see all the beautiful sights along the the way. Experience history when you arrive to the fort from 1894.

Middelgrundsfortet is the worlds largest manmade island and a unique part of the Danish history. The fort was established in the end of the 1800 century.

The Youth Island

In 2015 the scouts took over the fort with a vision to transform it into a youth island.

The Youth Island is a wild activity platform for all Denmarks youth - an island where everybody is welcome from 2019. Meet new friends, participate in events and be a part of the future solutions for society.
