The Lutherhaus in Eisenach is one of the oldest surviving half-timbered houses in Thuringia. Tradition holds that Martin Luther lived there with the Cotta family during his schooldays from 1498 to 1501. The Lutherhaus has been one of the most important historic Reformation sites since the 19th century and, as such, was designated a "European cultural heritage site" in 2011. The Lutherhaus has been run as a cultural history museum since 1956.
