Hafnia Hodierna, Eller Udførlig Beskrivelse om den Kongelige Residentz- og Hoved-Stad Kiøbenhavn (English: Hafnia Hodierna, Or Detailed Description of the Royal Residence and Capital City Copenhagen) is an engraved architectural work on Copenhagen, published by the Danish architect Lauritz de Thurah in 1748. Profusely illustrated throughout, it is a valuable source of knowledge as to the appearance of Copenhagen in the middle of the 18th century. It complements, with some overlap, de Thurah's other major work Den Danske Vitruvius, which focuses primarily on surrounding areas (such as Fredensborg), as well as the rest of Denmark. In 1967, Rosenkilde & Bagger published a facsimile edition, edited by Svend Cedergreen Bech. Hafnia Hodierna is Latin for "Copenhagen of today". Source: Wikipedia (en)
