The Apollinariskirche was built 1839-1842 on the site of the medieval Martinskirche. The frescos on the inside of the neo-Gothic church were painted by members of the artists group called the "Nazarenes". Three cycles show the life of Jesus, the life of Mary, and the history of Saint Apollinaris, legendary Bishop of Ravenna. In the crypt is a silver bust of the saint, which is raised from the sarcophagus every year at the pilgrimage time at the end of July. From the statue of Saint Francis of Assisi on top of the church, there is a lovely view of Remagen and the romantic Rhine Valley.
