It is a matter of extreme difficulty to decide how far this plan was followed in the erection of either the church or monastery of St. Gall at this remote period, for everything there has been altered at subsequent times; nor is it very important to enquire. The plan does not pretend to represent any particular establishment, but is a “projet” of what was then considered a perfect monastery. In this respect it resembles the plans of fortified towns which are engraved in our books of fortification representing the systems of Vauban, Coehorn, Montalembert, &c., and which, though applicable _mutatis mutandis_ to every place, have never literally been carried out in any one. It is in fact an illustration of the Benedictine system, as applicable to Germany in the ninth century, in its completed and most perfect form, and on this account is far more interesting to us than if it had been merely a plan of any particular monastery. The plan itself is on four sheets of parchment sewn together, and is so large (2 ft. 7 in. by 3 ft. 7 in.) that only a small portion of it can be reproduced here, and that on a reduced scale. The whole group of buildings was apparently meant to occupy a space of about 450 ft. by 300. On the north side of the church was situated the abbot’s lodging (B), with a covered way into the church, and an arcade on either face; his kitchen and offices being detached, and situated to the eastward. To the westward of this was the public school (C), and still farther in the same direction the hospitium or guest-house (D D), with accommodation attached to it for the horses and servants of strangers. Beyond the abbot’s house to the eastward was the dispensary (E), and beyond that again the residence of the doctor (F), with his garden for medical herbs and simples at the extreme corner of the monastery. To the eastward of the great church was situated another small double-apse church (G G), divided into two by a wall across the centre. On either side of this church was a cloister, surrounded by apartments: that on the north was the infirmary, next to the doctor’s residence, and to it the western portion of the chapel was attached. The other was the school and residence of the novices. Beyond these was the orchard (H), which was also the cemetery of the monks; and still farther to the southward were situated the kitchen-garden, the poultry-yard, the granaries, mills, bakehouses, and other offices. These last are not shown in the woodcut, for want of space. On the south side of the church was situated the great cloister (I), and further to the south of this was the refectory (J), with a detached kitchen (K), which also opened into the great wine-cellar (L); and opposite to this was the dormitory (M), with its various dependent buildings.
