Lacock Abbey in the village of Lacock, Wiltshire, England, was founded in the early 13th century by Ela, Countess of Salisbury, as a nunnery of the Augustinian order.

The abbey remained a nunnery until the suppression of Roman Catholic institutions in England in the 16th century; it was then sold to Sir William Sharington who converted the convent into a residence where he and his family lived. The house later passed into the hands of the Talbot family, and during the 19th century was the residence of William Henry Fox Talbot. In 1835 he made what may be the earliest surviving photographic camera negative, an image of one of the windows.
