Whorlton Castle

Whorlton was recorded in the Domesday Book of 1086 as belonging to Robert, Count of Mortain, half-brother of William the Conqueror, and later passed to the de Meynell family, who founded the castle in the early 12th century. In its first phase it was a wooden fortress on a roughly square motte some 60 by 50 metres, ringed by a dry ditch up to 20 metres wide and 5 metres deep behind an outer bank up to 2.5 metres high — most of the ditch survives, though its south-east quadrant has been destroyed by a modern road — and it adjoined a fortified enclosure taking in the village and church. In the 13th century it was known variously as Hwernelton or Potto Castle. The castle fell into disrepair or was dismantled during the first part of the 14th century; an account of 1343 describes it as a ruin.

In the mid-14th century Whorlton passed by marriage to John Darcy, Lord Darcy of Knayth, a figure with close ties to the royal court. Darcy levelled the motte and raised a new keep with a fortified gatehouse a short distance to the east; no evidence of a curtain wall survives, though centuries of stone-robbing may account for its absence. Above the gatehouse's main entrance are three carved shields — Darcy at the centre, flanked by Meynell and Gray — the Gray shield commemorating the marriage of Philip Darcy, 6th Baron, to Elizabeth Gray late in the century; a further shield above shows the arms of Darcy and Meynell impaled, marking the earlier match that had brought the castle to the family. The Darcys held Whorlton until 1418, when Philip Darcy's death passed it to his daughter Elizabeth and her husband Sir James Strangeways; the Strangeways family kept it until a dispute between heirs in 1541 made it a Crown possession.

Henry VIII granted the castle and estate to Matthew Stewart, 4th Earl of Lennox, whose eldest son Henry Stuart, Lord Darnley, would marry Mary, Queen of Scots. Margaret Douglas, Countess of Lennox, wrote to Mary in the autumn of 1561, possibly from Whorlton, to propose the match. Local tradition holds that the marriage contract was signed at Whorlton in 1565, but this is mistaken — it was actually signed at Stirling Castle in Scotland. In the late 16th or early 17th century the Lennox family built a house adjoining the gatehouse's north-west end, sketched in 1725 by Samuel Buck as a large two-storey building with gabled dormer windows; nothing of its structure survives beyond a roofline still visible on the gatehouse wall. The castle reverted to the Crown but fell into disrepair, and by 1600 was described as "old and ruinous". In 1603 the castle and manor were given to Edward Bruce, 1st Lord Kinloss; his second son, Thomas Bruce, 1st Earl of Elgin, was given the title Lord Bruce of Whorlton in 1641, and Thomas's son Robert became first Earl of Ailesbury in 1664.

By the early 19th century the keep's ruins had largely disappeared, as a lithograph of the period shows. The Bruce family retained the castle and manor until the late 19th century, when they were sold to James Emerson of Easby Hall, and in 1875 a large quantity of the castle's stonework was taken to build Swainby's village church. The castle is now privately owned, bought in the mid-20th century by Osbert Peake, 1st Viscount Ingleby, as part of a shooting estate; the site was scheduled as an ancient monument in 1928 and later listed Grade I, and the gatehouse received structural repairs from the Ministry of Works in the 1960s but has otherwise been left open to the elements.

The gatehouse, in poor condition and repeatedly vandalised, is on English Heritage's Heritage at Risk Register. It stands within the North York Moors National Park, and the Park Authority, English Heritage and the owner have worked on a conservation plan; a 2005 report recommended converting the gatehouse into a liveable property over the alternatives of retaining it as a managed ruin or handing it to a community group. English Heritage part-funded a feasibility study for that conversion, but the plan fell through when the Vivat Trust, which had proposed it, collapsed into administration. The castle is a Grade I listed building and a scheduled monument, privately owned but open to public visits.
