The Reiss-Engelhorn Museums (Zeughaus Museum) is more than just an exhibition space; it is one of the largest museum complexes in Germany, located in the historic center of Mannheim. The heart of the complex is the majestic building of the former arsenal (Zeughaus), built at the end of the 18th century. This late Baroque architectural monument houses approximately 1.2 million exhibits within its walls, covering vast segments of human history.

The museum complex, often abbreviated as REM, is named after its patrons, Carl and Anna Reiss-Engelhorn. Spanning over 11,000 square meters, it features four main thematic areas: archaeology, world cultures, art and photography history, and unique displays dedicated to music and theater. This venue is rightfully considered the main cultural hub of the region, offering visitors a fascinating journey through the centuries.
Of particular value are the collections of 17th-century Dutch painting, exquisite antique porcelain, and artifacts from ancient civilizations. As the last monumental building from the era when the city was the residence of the Electors, the Zeughaus Museum is a major exhibit in its own right, telling the story of the city's imperial past and its architectural ambitions.
