Swarthmoor Hall is a mansion in Swarthmoor, in the Furness area of Cumbria in North West England. Furness was formerly in Lancashire. It was the home of Thomas and Margaret Fell, the latter an important player in the founding of the Religious Society of Friends (Quaker) movement in the 17th century. The Hall is designated by English Heritage as a Grade II* listed building. It remains in use today as a Quaker retreat house.
Swarthmoor Hall was built by a lawyer named George Fell about 1568. The Hall was inherited by his son Thomas, a lawyer and later member of parliament, vice chancellor of the Duchy of Lancaster and an influential supporter of Parliament during the English Civil War. In 1634 Thomas married Margaret Askew and she moved into the Hall.
George Fox visited the Hall in 1652. Thomas Fell was travelling as a judge, but Fox had an audience with Margaret Fell, who became interested in his new doctrines. She arranged for him to preach in St Mary's Church in nearby Ulverston and at the Hall. During his time there, many people were convinced of the truth of his teachings.
When Thomas Fell returned home, he was persuaded by his wife and some others to listen to Fox, who successfully appealed to his pro-Parliamentary sentiments. Fell was never totally convinced by Fox's religious teachings, but he did allow his home to be used as a meeting house for the early Friends. Among those connected with the meeting were the missionary preachers Alice and Thomas Curwen, natives of nearby Baycliff, who were active in the Furness district, then in New England, Barbados and Nevis, and later in Huntingdonshire and other parts of England. The meeting continued to use the hall until 1691, when a meeting house was built nearby.
