Hallforest Castle is a keep, one of the oldest in Scotland, as it dates from the 14th century. The castle is believed to have been built by Robert the Bruce as a hunting lodge; he is said to have granted it to Robert II Keith, Marischal of Scotland, the predecessor of the Earls of Kintore. Mary, Queen of Scots visited Hallforrest in 1562.
The castle was frequently attacked during the 17th-century wars. It may have been abandoned shortly afterward, although it remains the property of the Earls of Kintore.
Hallforrest is a plain oblong tower 15 m long and 11 m wide. It once had a parapet, and probably a stone roof resting on an upper arch. It had two vaults, divided by entresol floors. It seems that the entrance led to the first entresol floor. There are small gun-loops to the basement, which may have had a cattle door.
Originally the castle had six floors. There are windows on the south. There is no evidence of masonry stairs; ladders and hatches must have been used. The interior is now ruinous.
To the north there are traces of what may have been an enclosing wall, and to the north west traces of a possible ditch or moat.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
