 But, perhaps because money was short, building progress was slow, and the church must have taken about sixty years to complete, going from east to west until the final portion was completed around 1220.The monastery was laid out according to the usual Cistercian plan, a church on the north side of a roughly rectangular cloister area, with a chapter house for meetings of the monks on a second side, a kitchen and a refectory on the third, and probably store houses and dormitory above on the fourth.But only small parts of the cloister survive, because it was turned into a barracks by the Elizabethans in 1592, and the Cromwellians who besieged it in 1645 and executed the remaining monks within.
