Батенберг, Palace and Regional History Museum in Ruse, Bulgaria.

Battenberg Palace is a palace and regional history museum in Ruse with a symmetrical neoclassical facade combined with Austrian baroque details and ornate stone carvings. Inside, it houses archaeological objects, historical documents, and regional artifacts representing different periods of Bulgarian history.

Architect Friedrich Grünanger designed the palace in 1882 as the official residence for Prince Alexander von Battenberg following Bulgaria's liberation from Ottoman rule. The building represented the nation's new independence and its emergence as a European power.

The building is popularly called Battenberg Palace after Prince Alexander I of Battenberg, for whom it was planned as an official residence in Ruse. It was finished in 1882, after his abdication, so no Bulgarian ruler ever lived in it; instead it housed the district administration and, from 1948, the District Court. Since 23 September 2007 it has held the Regional Historical Museum's exhibitions, opened by President Georgi Parvanov.

The palace stands at Batenberg Square 3 in central Ruse, in a park with fountains and sculpture compositions in front of it. The building has a large basement, once used for interrogations, and a tunnel once linking it to the nearby mayor's house. The museum reopened on 23 September 2007 after a renovation of about fifteen years.

The palace has a large basement where criminals and political prisoners were interrogated, and an underground tunnel once linked it to the nearby house of Ruse's mayor. The building was finished in 1882 but never housed a ruler: Prince Alexander I had already left the throne, so the district administration moved in instead.
