An arm of the Brukenthal Museum, this attraction is set in the Casa Altemberger, named after Thomas Altemberger who was mayor of Sibiu in the late 15th century.

The house, with mullioned windows and turrets, is one of the outstanding pieces of secular Gothic architecture in Eastern Europe.

From 1545 to 1948 it housed the Town Hall, while its tower contained the city archive throughout that period.
