the staterooms. Adam added a double staircase to the front of the house, and designed buildings on the estate, including the stable block. Nostell Priory is home to a large collection of Chippendale furniture, all made for the house and commissioned by Sir Rowland Winn 5th Bart and his wife Sabine Winn. Thomas Chippendale was born in Otley in 1718 and had workshops in St Martins Lane, London. The Nostell Priory art collection includes The Procession to Calvary by Pieter Brueghel the Younger, William Hogarth's Scene from Shakespeare's The Tempest - the first depiction in a painting of any scene from Shakespeare's plays - and a self-portrait by Angelica Kauffman, as well as Rowland Lockey's copy of the painting by Hans Holbein (c1527 but now lost) of Sir Thomas More and Family; this copy was commissioned in 1592 by the More family and came to Nostell in the 18th century, and is said to be the most faithful to the destroyed original. A longcase clock, with an almost completely wooden internal mechanism, made by John Harrison in 1717, is housed in the billiard room. Harrison, whose father Henry is thought to have been an estate carpenter, was born within half a mile of the estate. He was referred to as John "Longitude" Harrison, after devoting his life to solving the problem of finding longitude at sea by creating an accurate marine timekeeper. Known as H4, this chronometer can be seen at the Royal Observatory, Greenwich, London. In August 1982 there was a music festival there, sponsored and organized by Theakston's Brewery which was a great success. Two years later in 1984, there was another festival organized by a different group of people. Although this event was a commercial festival, the "Convoy" was involved in organising a free festival next to it. Riot police were mobilised to suppress this aspect of the event. In May 2007, a set of Gillows furniture returned to the house after refurbishment. These pieces now furnish the tapestry room, as do a pair of large Venetian vases, made of wood inlaid with ivory and semi-precious stones. The Adam stable block has undergone a major renovation and is now open as a visitor centre for the house and parkland. In June 2009 a suite of bedrooms on the second floor was handed to the National Trust. These bedrooms used by the Winns, had never been on public
