The hospitium, of which the upper part is of wood, contains a collection of Roman antiquities; the building is of the 14th and 15th centuries.
Other views of the original aerarii are that they were: - artisans and freedmen (Niebuhr); inhabitants of towns united with Rome by a hospitium publicum, who had become domiciled on Roman territory (Lange); only a class of degraded citizens, including neither the cives sine sufJragio nor the artisans (Madvig); identical with the capite censi of the Servian constitution (Belot, Greenidge).
In the Vennel (alley or small street) some ruins remain of the maison dieu, or hospitium, founded in 1256 by William of Brechin.
The Merveille (1203-1264) consists of two continuous buildings of three storeys, that on the east containing, one above the other, the hospitium (aumonerie), refectory and dormitory, that on the west the cellar, knights' hall (salle des chevaliers) and cloister.
The buildings devoted to hospitality are divided into three groups, - one for the reception of distinguished guests, another for monks visiting the monastery, a third for poor travellers and pilgrims. The first and third are placed to the right and left of the common entrance of the monastery, - the hospitium for distinguished guests being placed on the north side of the church, not far from the abbot's house; that for the poor on the south side next to the farm buildings.
There is also an "hospitium" for strange monks, abutting on the north wall of the church (Y).
Near the gate to the south was the guest-hall or hospitium (T).
These have been identified either with the hospitium or with the abbot's house, but they occupy the position in which the infirmary is more usually found.
Yspytty, spite, a corrupt form of the Latin " hospitium," often used of the guest-house of an abbey - Yspytty Ystwyth, Tafarn Spite.
