Thereafter the site of the abbey came into the possession of the Sondes family[3] and now lies within the grounds of Queen Elizabeth's Grammar School.
The Abbey was the burial place of King Stephen, Queen Matilda, and their eldest son, Eustace IV of Boulogne.
However, there is a canopy tomb with no contemporary inscription in the nearby Parish Church, where it is said that their bones were re-interred.
The abbey was built from a mix of chalk, flint, ragstone, greensand, and Caen stone.
The walls covered huge amounts of box flue tiles, which were used to direct hot air up the indoor walls, glazed terracotta floors, an untouched underfloor with hypocaust heating and tons of ceramic roof tiles.
