Found close to the center of Treis-Karden, Stiftskirche St. Castor is regarded as one of the town’s main churches. Some of the notable features inside this church include St. John's altar, St. Stephen Altar and the altarpiece that has depictions from the Bible.
This church, also called Westerwald Cathedral, is one of the most beautiful examples of neo-Gothic sacred architecture.
The Pallottine Church, an impressive example of expressionist architecture, was constructed by Hubert Pinard between 1925 and 1927. This type of a three-aisled basilica and the double tower facade adheres to the traditional architectural designs of Christian church buildings, but the shape of the parabolic arch that dominates the central nave creates a completely new impression of a cavernous space.
The current St. Lubentius and Juliana Collegiate Church was built at the turn of the 11th century. In the 12th century the choir was modified and two towers in the west replaced the original single-tower facade. In the same century, the nave was converted into a basilica featuring galleries. Perched on a hill above the countryside, this building is still an excellent example of Romanesque architecture despite some modifications.
