I just love buildings like this: standing proud, gnarled and weather-beaten with a layered and textured patina that sees one epoch crash into another. Ghost gables abound, and walls that were once inside are now outside.
Pershore Abbey is a hidden gem. You can spend a delightful day there exploring the abbey and the town which has some wonderful Regency brick architecture (and a few timber-framed delights).
The Abbey Church of Holy Cross or Pershore Abbey has a wonderful vaulted interior of the C13th with tierceron vaults that explode like fireworks.
