§ 68. The chief peculiarities of the Cistercian plan were without influence on the houses of other orders, which adhered to Benedictine precedent in such points as the position of the warming-house, frater and kitchen. Thus the plan of the Augustinian house of Haughmond, allowing for special exigencies of site, is that of a Benedictine monastery, with the exception that the building between the church and chapter-house appears, as at St Agatha's and many smaller monasteries, to have been a sacristy, while the canons' parlour, as again at St Agatha's and at Repton, was in the Cistercian position, south of the chapter-house. At Alnwick the sacristy and parlour stood side by side south of the church. Variations may be found in such points as the connexion of the dorter with the church: in the Carmelite friary of Hulne, for example, the night-stair opened, not into the church itself, but into a small court next it. But the collation of plans, such as those of the Augustinian St Frideswide's at Oxford and the Premonstratensian St Radegund's at Bradsole, with those of other orders, shews clearly that the arrangement of canons' and friars' cloisters was modelled upon the convenient Benedictine plan. The same conclusion applies to nunneries, as may be gathered from the foregoing pages. Little is known of the buildings of Cistercian nunneries, but the nuns' cloister at Watton was upon the Benedictine plan, with the exception that the ground-floor of the western range was probably the house of the lay sisters. The canons' cloister was very similar in plan; but its vaulted chapter-house, like others already mentioned, may shew the architectural influence of the Cistercian order. The two cloisters were connected by a long passage, in which was the turning-window (_fenestra versatilis_), where necessary communication was carried on between the two divisions of the monastery.
