Osterspai, located opposite the left bank Jakobsberg near Boppard, is a gem for pilgrims on the Way of St. James. And of course not just for them, as the picturesque village has already won several awards in the category 'Our Village Should Become More Beautiful'. In addition, the Way of St. James from Braubach to Osterspai - also part of the Rheinsteig and sectionally the Rheinhöhenweg - offers fascinating views of the Rhine panorama.

The chapel in the castle garden is used for church services as well as for religious or civil weddings and baptisms.
