In the historic monastery, which formerly housed the Catholic Arnstein Fathers, there are lovingly renovated apartments and office spaces.

In 1906, the Johannis Church was integrated into a monastery complex (Johannis Monastery). The monastery was closed and privatized in 2007. The Johannis Church is now maintained by the parish of St. Martin & St. Damian Rhein Lahn, Lahnstein.

The property "Catholic Monastery Church St. John the Baptist and Johannis Johannesstraße" is a listed monument (Monument Register Rhein-Lahn-Kreis, p. 51).
