The impressive remains of an abbey founded by Stephen, later King of England, including much of the east end and west tower of the church, the ornately decorated chapter house and the cloister buildings.
English Heritage is carrying out emergency conservation work to stop the ruined Abbey church sinking into the soft ground. This follows earlier routine inspections which revealed serious cracks in the walls. Medieval masons used large pieces of oak in the foundations and after 500 years, this timber is now gradually giving way.
