The Niederburg ruins ('Lower Castle') at Kobern stand at a height of about 150 metres above the village of Kobern on a hill ridge that points towards the Moselle. On the same ridge and about 50 metres higher, is the Oberburg ('Upper Castle') and St. Matthias' Chapel.
The castle has an amygdaloidal ground plan. It has a three-storey, 20-metre-high bergfried, measuring 7.5 x 8 metres, with an elevated entrance at a height of 10 metres. There are also the remains of a two-storey, Late Gothic palas. A wall tower and a cistern are also well preserved and there are significant portions of the outer walls. The castle was guarded to the west by a curtain wall with a zwinger and to the north by a throat ditch. The upper third of the bergfried and the battlements were rebuilt in the 19th century. Between 1976 and 1978, the state castle administration reconstructed and enhanced the palas and the cistern between the two towers.
The castle was built in the mid-12th century. It is first recorded in 1195, when the then Burgherr made it a fiefdom of the Electorate of Trier. The female line of the lords of Isenburg-Kobern died out in the 13th century. The Kobern Castles and associated lordship passed via the heiress, Cecilia, to Frederick II of Neuerburg (a side line of the counts of Vianden). In 1309 the male line of this family also died out. Thereafter the castle and lordship was sold to the Archbishop of Trier. In 1688 the castle was destroyed.
The castle is open to the public all year round and may be visited free of charge. Visitors may climb up to the castle on a footpath from the Mühlbach valley.
References:The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
