The Rousse Regional Historical Museum is one of the 11 regional museums of Bulgaria. It acts within the Rousse, Razgrad, and Silistra regions. The museum occupies the building of the former Battenberg Palace, previously a local court, built 1879–1882 by Friedrich Grünanger.
The Rousse Regional Historical Museum was established in 1904. Its basis are the archeological collections of Karel and Hermenguild Shkorpil, as well as of the naturalist Vasil Kovachev, which were gathered in the "Knyaz Boris" men's high school of Rousse.
