Fountains Abbey
The original abbey church was built of wood and "was probably" two stories high. It was, however, quickly replaced with stone. The church was damaged in the attack on the abbey in 1146 and was rebuilt as a larger church on the same site. Building work was completed c.1170. This second church was completed around 1170. It was  long , made up of 11 bays.  The infirmary (marked "Abbots House" on the plan) had  one of the largest halls in England in the middle ages , It had its own chapel and kitchens. Parts of it are on top of tunnels where the River Skell flows.
