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:Dryburgh Abbey on the banks of the River Tweed in the Scottish Borders was founded in 1150 in an agreement between Hugh de Morville, Constable of Scotland, and the Premonstratensian canons regular from Alnwick Abbey in Northumberland. The arrival of the canons along with their first abbot, Roger, took place in 1152.
It was burned by English troops in 1322, after which it was restored only to be again burned by Richard II in 1385, but it flourished in the fifteenth century. It was finally destroyed in 1544, briefly surviving until the Scottish Reformation, when it was given to the Earl of Mar by James VI of Scotland. It is now a designated scheduled monument and the surrounding landscape is included in the Inventory of Gardens and Designed Landscapes in Scotland.
David Erskine, 11th Earl of Buchan bought the land in 1786. Sir Walter Scott and Douglas Haig are buried in its grounds.
