Crookston Castle is surrounded by a defensive ring-ditch that dates back to the 12th century when Sir Robert de Croc, who also gave his name to the village of Crookston, built a timber and earth castle. Remains of a chapel founded by de Croc in 1180 have been uncovered. Evidence of an even earlier fortification on the same site has also been found. The lands of Crookston were bought by Sir Alan Stewart in 1330, and passed to Sir John Stewart of Darnley, in 1361. The Darnley Stewarts replaced the early castle with the present stone structure around 1400.
In 1489 the Stewart Earl of Lennox rebelled against James IV. James responded by bringing the cannon Mons Meg from Edinburgh and bombarding the castle, virtually destroying its western end and ensuring a quick surrender. In 1544 the castle was besieged and taken by the Earl of Arran and Cardinal Beaton, while the then Earl of Lennox was defending Glasgow Castle. At this time, Crookston was regarded as the principal house of the earls of Lennox.
Most famous of the Darnley Stewarts was Henry Stuart, Lord Darnley, who was second husband to Mary, Queen of Scots. It may have been at Crookston that the couple were betrothed, under a yew tree. The yew was felled in 1816, and a model of Crookston Castle, now on display in Pollok House, was carved from its wood. In 1572, Crookston was granted to another Stewart, Charles, the Earl of Lennox.
In 1703 the Duke of Lennox sold the castle to the Duke of Montrose, and it remained the property of the Dukes of Montrose until 1757, when it was sold by William Graham, 2nd Duke of Montrose to the Maxwells of Pollok. Following several years of abandonment, the castle was partially restored by the Maxwells in 1847, to honour Queen Victoria's visit to Glasgow. In 1931, Crookston became the first property acquired by the National Trust for Scotland, having been presented by Sir John Maxwell Stirling-Maxwell, who was one of the Trust's founder members and first Vice Presidents.
Today, Crookston Castle is a scheduled monument. Its maintenance is the responsibility of Historic Environment Scotland, and the castle is open to the public. It is the second-oldest building in Glasgow, after Glasgow Cathedral.
Crookston Castle sits atop a natural hill, emphasised by the early ring-ditch, which can still be seen. To the north is a steep drop to the Levern Water. The castle has a rectangular main block, which was strengthened by a tower at each corner. This formed an irregular 'X-plan' shape, an unusual layout also seen at Hermitage Castle. Only the north-east corner tower survives to its former height, as well as the basement of the south-east tower. The two western towers were destroyed in the 15th century and never rebuilt, repairs in the 19th century have obscured even the remains of these. The main body of the castle measures about 19m by 12m, with walls up to 3.7m thick, and the north-east tower is around 6m square.
The entrance is on the north side, adjacent to the north-east tower, and defended by a portcullis and two doors. A straight mural stair leads up to the right, while ahead is a barrel-vaulted basement with slit windows and a well. The hall is at first-floor level, and was also vaulted, rising to 8.3m high. A turnpike stair in the south-east corner gave access to another storey above the hall, as well as upper rooms in the eastern towers. The towers had one room on each floor. In the basement of the north-east tower is a prison only accessible from above, while at the top there is access to the four storeys of the tower, via modern iron ladders, opening onto an impressive view from the roof. The top of the north-east tower, including corbels, was also rebuilt in the 19th century.References:
The Château d'Olhain is probably the most famous castle of the Artois region. It is located in the middle of a lake which reflects its picturesque towers and curtain walls. It was also a major stronghold for the Artois in medieval times and testimony to the power of the Olhain family, first mentioned from the 12th century.
The existence of the castle was known early in the 13th century, but the present construction is largely the work of Jean de Nielles, who married Marie d’Olhain at the end of the 15th century.
The marriage of Alix Nielles to Jean de Berghes, Grand Veneur de France (master of hounds) to the King, meant the castle passed to this family, who kept it for more than 450 years. Once confiscated by Charles Quint, it suffered during the wars that ravaged the Artois. Besieged in 1641 by the French, it was partly demolished by the Spaniards in 1654, and finally blown-up and taken by the Dutch in 1710. Restored in 1830, it was abandoned after 1870, and sold by the last Prince of Berghes in 1900. There is also evidence that one of the castles occupants was related to Charles de Batz-Castelmore d'Artagnan, the person Alexandre Dumas based his Three Musketeers charictor d'Artagnan on.
During the World War I and World War II, the castle was requisitioned first by French troops, then Canadian and British soldiers. The current owner has restored the castle to its former glory.
