Engelstein Castle

The castle only appears in documents around 1417, but is likely to be significantly older. Presumably, a simple watchtower stood in its place before.
After the destruction of Hadmarstein Castle on the neighboring Johannisberg, the tower at Engelstein was probably expanded into a moated castle in the second half of the 13th century.
