Vilhelm Dahlerup's building from 1868 for the Port Authority marks the western boundary of the quayside space at Nordre Toldbod. The design was inspired by Italian Renaissance architecture and the building originally consisted of two stories with a small one-story appendix topped by a balustrade on each side. The original building was extended with an extra floor by Einar Madvig and now consists of a three-story main building with two low lateral wings in 1939, and a rear wing was added in 1901. The building is now the head office of By & Havn.
