8. Niederfell to Koblenz

The parish church of St. Lambertus was built in 1792 with a ridge turret and enlarged in 1871 and 1872. The tower dates from 1955 and the church is dedicated to St. Lambertus, bishop and martyr, 7th/8th century. The church is under monumental protection.
Worth seeing: the group of baroque altars from 1773, consisting of a high altar and two side altars, from the former church of the Mariarod monastery. They were brought to Niederfell by the French in 1795 when the monastery was destroyed by the citizens of Niederfell with ox carts.

In Biedlich, near the church, there is an old castle house with a remarkable hipped roof and a double row of dormer windows - the Heesenburg. It dates from the 13th century and belonged to the family of Koblenz von der Arken. In 1514 Marsilius von Arken sold the estate to the Muhl von Ulmen family. Baron Johann Philipp Ernst von und zu der Hees inherited the castle in 1762. The east side has a one-storey half-timbered building with a dwarf gable, while the southwest corner has one of the four original oriels, which were reconstructed more recently as an octagonal half-timbered structure.

The Church of Our Lady (Liebfrauenkirche) is a Catholic church in the centre of Koblenz' Old Town. Together with the two other Romanesque churches, the former collegiate churches St. Kastor and St. Florin, it dominates the silhouette of the old town. The beginnings of the church, which is located at the highest point of the Old Town, date back to the 5th century. From the late Middle Ages to the French Revolution, it was the main parish church in Koblenz. It bears the patronage of Mary, the mother of Jesus, and is a major work of medieval sacred architecture on the Middle Rhine.
An earlier building to the Liebfrauenkirche dating from the 5th century is a hall from the time of Emperor Valentinian I (364-375). Within the walls of this Roman building, the Franks, who came to Koblenz at that time, established a Christian place of worship. Using the foundations, this church underwent several alterations and extensions.
Around 1180 a Romanesque church was built on the site of the Roman building. In the 15th and 16th centuries the Gothic edifice was extensively altered. In 1694 the bell towers were rebuilt. The bombings of 1944 severely damaged the building.

The Florinskirche is a protestant church in the old town of Koblenz. Built around 1100, the church building, which dominates the skyline of the city, belonged to the canonical monastery of St. Florin, which was secularized in 1802. Later, in 1820, it became the first church building in Koblenz to be consecrated as a Protestant church in the Rhineland. The early medieval church building is an excellent example of sacred Romanesque architecture on the Middle Rhine.
On this 6th century site there was a royal chapel dedicated to the Virgin Mary. At the beginning of the 10th century, after the transfer of Florin's relics from Remüs (Switzerland), the church was consecrated to St. Florin.
Around 1100 a new Romanesque church was built and in the 14th century the Romanesque apse of the church was replaced by a Gothic apse. In the years 1582 to 1614 the vaulting of the eastern nave followed. At the beginning of the 17th century, the bell towers were renovated but in 1791 lightning and fires damaged the bell towers, necessitating the reconstruction of their upper parts. The pointed roofs date from the end of the 19th century.
In 1794 French revolutionary troops occupied Koblenz during the first coalition war. The Abbey of Saint-Florin was secularised by the French in 1802 and thus suppressed. Subsequently, the church building was used as a military storehouse.
King Frederick William III transferred the building to the Protestant military and civil community in 1818.

The Church of St. Kastor (St. Kastor or Kastorkirche in German) is the oldest church in Koblenz. Dedicated to Castor of Karden, it is situated behind the Deutsches Eck. On the square in front of the basilica is the Beaver Fountain from the Napoleonic era.
The confluence of the Moselle and the Rhine has been a historical site since Gallo-Roman times. Several treaties were signed at this location, including the Treaty of Verdun in 843 and the Peace of Koblenz in 860.
In the 9th century the basilica replaced a Gallo-Roman temple, this first church occupies the surface of the current nave. Damaged in the 12th century, it was restored in the 13th century.
Between 1496 and 1499, the basilica underwent the last major alterations, with the change of the ceiling of the nave, which became a ribbed Gothic vault. When the French invaded the region in 1802, they secularised most of the abbeys, such as the church of Saint-Castor, which had been a collegiate monastery until then, and became a simple parish church.
Heavily damaged by the bombings of 1944, it was restored during the second half of the 20th century. The parish church was elevated to the rank of Basilica in 1991.
St. Castor of Karden (5th century): Probably originally from Aquitaine, Castor became a disciple of Maximin of Trier who ordained him a priest. He settles in Treis-Karden, perhaps as a hermit. In the company of St. Potentinus, an Aquitanian like himself, he may have founded a monastic community;
In 837, Bishop Hetton of Trier had his relics transferred to the Basilica of St. Castor in Koblenz, the city of which he became patron saint.
