Fortunstræde 1 is a Neoclassical property situated at the corner of Fortunstræde and Admiralgade, opposite the former St. Nicolas' Church, now Kunsthallen Nikolaj, in central Copenhagen, Denmark. The building was like most of the other buildings in the area constructed after the Copenhagen Fire of 1795. It was shortly thereafter acquired by the bookseller Abraham Soldin who in partnership with his brother Salomon Soldin ran a bookshop and publishing business from the premises. The venture was later continued by his son Ferdinand Vilhelm Soldenfeldt as F. V. Soldenfeldt. The building is today owned by Borgervennen, a fraternal society founded in 1788, now based in the apartment on the first floor. The building was listed in the Danish registry of protected buildings and places in 1945.
