Remagen
Overlooking the west bank of the Rhine just north of the city centre is a church called the 'Apollinariskirche'. It has an observation deck that is only open to parishioners on Sundays. Walkers reach the church via a dirt track that passes a series of roadside monuments. One for each of the fourteen Stations of the Cross. The church grounds contain an outdoor crypt and an abbey. Further down the river is one of the many castles along the River Rhine, perched even higher than the Apollinariskirche.
