Among the best-known buildings of Germantown are the sturdy, elegant stone structures known today as Cliveden, the Johnson House, the Germantown Mennonite Meeting House, and the Concord School House. Remarkably, these structures can all be attributed to one builder, Jacob Knorr. This tour will bring visitors to these charming and significant sites and investigate what we know about the building of early Germantown, and what mysteries remain. In the case of inclement weather, this tour will be rescheduled.
