Mederův dům, Medieval house in Žatec, Czech Republic

Meder House is a residential building in Žatec that contains architectural elements from several different styles and periods. The house features a historic kitchen where objects from various periods of the town's past are displayed, along with cellars that remain from earlier building phases.

The house is first documented in 1564, when it belonged to Regina Bříšková, but its core is a Gothic structure probably from the 14th century, later altered in the Baroque period after Žatec's fires. Owners declined from wealthy burghers to residents unable to fund repairs, which preserved the medieval layout. In 1919 it was bought by the German Meder family, who gave it its name. Roof and trusses collapsed in the early 1980s; the Spolek Mederova domu, founded in 2016, restored it by 2020 for 24 million crowns.

The house is named after the German Meder family, who bought it in 1919; during the First Republic they gave tours of the building to curious visitors. The ground floor now holds an exhibition on medieval living, the first floor is furnished as around 1900, and the attic is devoted to the Žatec herbalist Marie Treben. Visitors can try on historical costumes, sleep on a straw mattress or grind coffee on a historical mill.

During the 2019–2020 reconstruction, four coins from the 16th and 17th centuries and the bones of a small animal were found in the house. The oldest coin dates to 1569 and the youngest to 1645; the bones were likely an offering meant to bring luck to the house and its residents.
