Dynge Castle, also Dyngehus as it was once called, was a Norwegian fortified castle in use from approximately 1250 and onwards towards the beginning of the 16th century, when it burnt down. Located in central Bohuslän, since then passed into Swedish possession, the castle was mentioned several times in Norwegian records. The site was excavated 1912-1913 by Wilhelm Berg, who had also excavated the contemporary and largely similar castle Ragnhildsholmen Castle during the 1880s, and Olsborg Castle. Since then, the site has had no closer examination by archaeologists.
The castle was in shape similar to a motte-and-bailey, with a stone keep surrounded by a small moat, standing on top of a cliff overlooking Gullmarsfjorden. The foundations of the central keep's walls remain clearly visible, as does the moat. It is one of few remaining medieval structures in Uddevalla Municipality, alongside Dragsmark Abbey and Bokenäs Old Church.References:
Dunluce Castle is a ruined medieval castle located on the edge of a basalt outcropping in County Antrim, and is accessible via a bridge connecting it to the mainland. The castle is surrounded by extremely steep drops on either side, which may have been an important factor to the early Christians and Vikings who were drawn to this place where an early Irish fort once stood.
In the 13th century, Richard Óg de Burgh, 2nd Earl of Ulster, built the first castle at Dunluce. The earliest features of the castle are two large drum towers about 9 metres in diameter on the eastern side, both relics of a stronghold built here by the McQuillans after they became lords of the Route.
The McQuillans were the Lords of Route from the late 13th century until they were displaced by the MacDonnell after losing two major battles against them during the mid- and late-16th century.
Later Dunluce Castle became the home of the chief of the Clan MacDonnell of Antrim and the Clan MacDonald of Dunnyveg from Scotland.
In 1588 the Girona, a galleass from the Spanish Armada, was wrecked in a storm on the rocks nearby. The cannons from the ship were installed in the gatehouses and the rest of the cargo sold, the funds being used to restore the castle.
Dunluce Castle served as the seat of the Earl of Antrim until the impoverishment of the MacDonnells in 1690, following the Battle of the Boyne. Since that time, the castle has deteriorated and parts were scavenged to serve as materials for nearby buildings.
