Durris Castle, also known as the House of Dores, was an early royal residence on the southern bank of the River Dee in Aberdeenshire, Scotland. The site consisted of a medieval motte and bailey castle and controlled the northern end of the Crynes Corse Mounth trackway.
Dating from at least the 13th century, the castle, a motte and bailey, was occupied by Alexander III and is mentioned in the Chamberlain Rolls of the time as the subject of repairs. King Edward I of England stayed one night in 1296 at the castle, during his invasion of Scotland. Durris was granted to the Fraser family by King Robert I of Scotland and created into a barony by King David II of Scotland.
It was burned by the Marquis of Montrose in 1645 and not rebuilt.
No remains of the castle exist today, but the 7-metre-high conical knoll on which it stood retains the name Castle Hill. The hill has a flattened summit measuring 41 metres by 30 metres, and its sides may have been artificially steepened. Evidence remains on the western side of the site of a 2.6 metre ditch, possibly a moat.
