It was associated with local fraternities or [[guild]]s in the 15th century and could seat 1,000 people at a time. Severely damaged by World War II bombing, the church was subsequently restored. In 1950 it was listed as a Grade I building.<ref name="BLB">{{cite web|url=http://www.britishlistedbuildings.co.uk/en-175193-church-of-all-saints-lydd-kent|title=Church of All Saints, Lydd|publisher=British Listed Buildings|access-date=14 October 2012|archive-date=3 September 2014|archive-url=https://web.archive.org/web/20140903111945/http://www.britishlistedbuildings.co.uk/en-175193-church-of-all-saints-lydd-kent|url-status=live}}</ref>

Lydd church, with its tall tower, was a major link in the chain of [[trigonometric]] measuring points for the [[Anglo-French Survey (1784–1790)]]. This connected the [[Royal Greenwich Observatory]] and the [[Paris Observatory]]. This eighteenth-century survey was led by General [[William Roy]]. It included a secondary base-line for checking purposes on [[Romney Marsh]], between [[Ruckinge]] and [[Dymchurch]]. The primary base-line was on [[Hounslow Heath]]. All Saints' Lydd was the main intermediate point on the south coast between [[Fairlight, East Sussex|Fairlight Down]] to the west and [[Dover Castle]] to the east.
