House of the Wannsee Conference, Historical museum in Wannsee district, Berlin, Germany.

This villa in the Wannsee district became the site where Nazi officials coordinated plans for mass deportation and murder in 1942. The exhibition spaces display original documents, photographs, and multimedia materials that detail the persecution and systematic killings of European Jews.

The villa was built in 1915 for the manufacturer Ernst Marlier. From 1941 to 1945 it served as a guest house and conference centre for the SS. On 20 January 1942 fifteen senior representatives of the SS, Hitler's secret police and several Nazi ministries met in the former dining room to plan the deportation and murder of Europe's Jews. The house opened as a memorial museum on 19 January 1992.

The permanent exhibition centres on the 20 January 1942 meeting held in the villa's former dining room, where fifteen senior SS, Gestapo and ministry officials planned the deportation and murder of Europe's Jews. Since 1992 the house has held a memorial, a documentation centre and a library, with workrooms for visiting groups.

The house stands at Am Großen Wannsee 56–58, on the lake's shore in Berlin's Wannsee district. Reach it by S-Bahn to Wannsee station, then bus 114 to the house. The permanent exhibition is on the upper floor; the former dining room where the conference took place is on the ground floor. Group workrooms and a library are available by arrangement.
