Gresham castle was built by Sir Edmund Bacon in 1319, but it stood on the site of an earlier castle. It was forty metres square with round corner towers and a surrounding moat. It pass to the ownership of the Paston family who faced considerable argument and armed oppression in seeking to retain it and Margaret Paston recalls in her letters how Lord Moleyns attacked the castle with an overwhelming force and threw her out. The Paston family did eventually recover ownership and a letter of one of the John Paston's suggests he was looking at the possibility of rebuilding what Moleyns' men had knocked down. However, this was not to be and today, under considerable vegetation, only a metre to a metre and a half of the flint walls remain. In stands on private land and is watched by English Heritage. In the course of the Paston Footprints project, a 3D model of the building is being constructed on screen and the drone photography for this image is part of that process.
