Jenisch Haus is a palace and a museum in Hamburg. It is an old country house built in neoclassic style by the Hamburg merchant Martin Johan Jenisch, between 1831 and 1834. The building looks like a three-storey building with a monumental portico supported by Doric columns, which overlooks on the Elbe River. The architect in charge was Franz Gustav Forsmann, but Schinkel himself (the most important architect of German neoclassicism) personally revised the project. Inside, the halls are decorated with rich stuccos, luxurious furniture, paintings and sculptures of the time: the original appearance of the villa has been maintained and can now be visited, testifying to the refined lifestyle of the wealthy 19th-century Hanseatic citizens. The villa was transformed into a museum in 1936 and is now a branch of the Altonaer Museum, often home to temporary exhibitions. Concerts and events for children and families are also organized in the Jenisch Haus, such as the puppet theater.
