Company profile
National and international real estate project developer from Bremen
denkmalstadt GmbH (formerly Überseeinsel GmbH) develops projects in Bremen, Hamburg, Lübeck, and Hanover, as well as on Rømø (DK), Norderney, and Borkum.
The company was founded in 2018 as Überseeinsel GmbH for the transformation of the former Kellogg's production site in Bremen into a healthy, vibrant, safe, and ecological urban district.

The company remains committed to developing livable places characterized by sustainable energy supply, diverse architecture, and a mix of uses.
