Liebenburg Castle with its tower and the remains of its wall on Schlossberg near Eisweiler is the landmark of the municipality of Namborn. It was built at the end of the 12th century by Bliesgaugrafen von Castel by order of the diocese of Verdun. The castle was first mentioned in documents in 1220, when the Bishop of Verdun appointed the knight 'Boemund de Lievenberc' as castle guard. The castle came into the possession of the archbishops of Trier in around 1400, who pledged the castle to solvent noble families due to a lack of money. From 1677 to 1696, the castle was pledged in ownership to the lords of Sötern. It was during this period that the castle was finally destroyed.
From the castle tower, you have a wide view of the surrounding area of Sankt Wendel County.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
