Tjuvholmen

[1] The area was bought by the shipyard Akers Mekaniske Verksted in the mid 19th century, who planned to build a drydock there.

They built docks and artificial land, increasing the area from 5 to 33 hectares (12 to 82 acres).

Olsen & Co. rented the docks, and from 1971 Nylands Mekaniske Verkstad had a shipyard on the spot.

Since 2005, the area has been sold to private developers, who are conducting an urban renewal with housing.

The German geologist Leopold von Buch visited the area in 1806–07, and he then discovered and described rhomb porphyry for the first time.
