Lamel Hill, once known as Heslington Hill, is about 1 mile south-east of the centre of York. It is near The Retreat and the northern part of Walmgate Stray. It is best known for having been the location of a Parliamentary gun-emplacement aimed at Walmgate Bar in the City Walls during the Siege of York in 1644. It was the site of York's first formal archaeological excavation in 1849, when traces of an Anglo-Saxon cemetery were found.
