Red Castle, Angus
The earliest structure on the site was built for King William the Lion in the late twelfth century to repel Viking invasions to Lunan Bay. Evidence shows, however, that William took up residence there on several occasions whilst on hunting expeditions. In 1194, William conferred the castle, and land surrounding the village of Inverkeilor, 2 kilometres (1.2 mi) east of the castle, to Walter de Berkely, the Royal Chamberlain. In 1328, Robert the Bruce gave the castle to the Earl of Ross. The castle is referred to as rubeum castrum (Latin for Red Castle) in deeds of 1286, referring to its burnished red sandstone, typical of this area.
In 1579, James, son of Lord Gray, married Lady Elizabeth Beaton, who owned the castle, and fell in love with her daughter. After Lady Beaton threw him out, Gray (with his brother Andrew of Dunninald) laid siege to the castle for two years, ultimately burning the inhabitants out. From then on the castle slipped into decline, and, although it remained partially roofed until 1770, it was never again a residence of nobility. Its last inhabitant was the minister of Inverkeilor, one James Rait.
Red Castle stands on high ground overlooking Lunan Bay, on the North Sea coast. Immediately to the north of Red Castle is the mouth of the Lunan Water, with the hamlet of Lunan beyond. Only a part of the fifteenth century rectangular tower, and the 2-metre (6.6 ft) thick east curtain wall remain. The tower in particular is in precipitous condition, being perched on the edge of the hill above Lunan Bay, and was described as being "in imminent danger of collapse" in 1999. The castle is clearly visible from the A92 road. The remains are those of the 15th-century keep, and the surrounding wall, or enceinte, which may date from the 13th century. A midden below the castle is continually eroding, yielding a number of artefacts now in the Montrose Museum. The tower and enceinte are both protected as category A listed buildings.
