This paper aims at discussing the spatial development and historical buildings of Nowe Miasto Lubawskie since 1939. It presents the history, architecture and modern state of objects (especially monuments) that shape the historical landscape of Nowe Miasto Lubawskie. Buildings that have not survived to this day are also discussed. Moreover, the memorial places in the town are presented here; the above chronological limitations do not apply to this aspect. Apart from a monography on Nowe Miasto Lubawskie, the paper refers to, among others, archival materials from the State Archives in Olsztyn and the archives of the voivodeship’s Monuments Protection Office in Olsztyn (Branch in Elbląg), tourist guides, information bulletins, articles in local Nowe Miasto papers and photography–based documentation. The core of the article is preceded by a short characterisation of Nowe Miasto Lubawskie and a description of the changes of its administrative affiliations over the centuries.
