The Old Latin School (OLS) is at the physical and spiritual center of the community, directly adjacent to the St. Mary’s City Church, or Stadtkirche, where Luther preached more than 2,000 sermons and which is known as the “Mother Church of the Reformation.” The OLS is also within easy walking distance of the former university buildings where Luther taught, his home, the Castle Church, or Schlosskirche, where Luther nailed his 95 Theses and is buried, and other Reformation landmarks. Situated just off the town market place, visitors are able to walk to historic sites as well as to stores, banks and restaurants.
