Addington Palace is an 18th-century Palladian mansion near Croydon in south London, built on the site of an earlier manor house from the Leigh family.
 
The current house was constructed starting in 1774 by Barlow Trecothick, a former Lord Mayor of London originally from Boston, with design by Robert Mylne; it was completed by his nephew James Trecothick. From 1807 to 1897, it served as the summer residence for six Archbishops of Canterbury after Croydon Palace fell into disrepair, during which they renamed it Addington Farm (later Palace) and expanded it under architects like Richard Norman Shaw. The estate hosted royals including Queen Victoria and saw Capability Brown landscape the grounds in 1782.
