The entire four-storey building has cellars, and the tall cellar rooms are covered with barrel vaults resting on rectangular pillars. The neighbouring townhouse No. 4 is younger – it dates from after 1635. It was partly built on the site of the former churchyard.
The gables of the other townhouses on the Market Square, which no longer exist, echoed the eastern elevation of Stargard’s Town Hall, rebuilt in 1654. Its early Baroque gable was given horizontal divisions harmonised with the late Gothic western gable. This solution became a model for Stargard’s burgher architecture and remained popular for the next hundred years. Another characteristic feature of Stargard townhouses were two-storey oriels, placed asymmetrically in relation to the axis of the façade. This set the local architecture apart from that of other Pomeranian towns.
Both townhouses belonged to merchant families and were bought by the town at the beginning of the 20th century. After the destruction of 1945, their interiors were rebuilt and adapted for museum use in the 1960s. Today they house the Archaeological and Historical Museum in Stargard.
