The Museum of History of Polish Jews is a new museum on the site of the former Warsaw ghetto. The cornerstone was laid in 2007, and the museum was first opened on April 19, 2013. The museum will feature multimedia exhibits on vibrant Jewish community that flourished in Poland for a thousand years. The building, a postmodern structure in glass and limestone, was designed by Finnish architects Rainer Mahlamaki and Ilmari Lahdelma.
