Officially part of the Brukenthal Museum, Sibiu's History Museum is found in the Casa Altemberger, opposite the Evangelical Church; For more than 400 years (until 1948) this was Sibiu's Town Hall. The building hosts a number of exhibitions spread over three floors, from the lapidarium in the basement (featuring pieces from the Roman period) to the collection of coins in the tower. Particularly good is the exhibition devoted to the Romanian National Movement of the 19th century, which campaigned tirelessly to encourage and develop a Romanian national consciousness amongst Romanians living in the Hapsburg Empire. Not be missed either is the collection of glass ornaments either made or found in the Sibiu region. Many come from the famous glass works at Porumbacu de Sus, a short distance east of Sibiu.
