The extensive buildings of the Cistercian abbey of Fontfroide, near Bizanet, include a Romanesque church, a cloister, dormitories and a refectory of the 12th century.
To left and right, and at the back, dormitories are excavated opening on to this hall, and in the centre of the back, facing the entrance, an image of the Buddha usually stands in a niche.
The number of dormitories varies according to the size of the hall, and in the larger ones pillars support the roof on all three sides, forming a sort of cloister running round the hall.
On the sides are grouped buildings for each individual professor and dormitories for students.
The principal buildings of the university are Packer Hall (1869), largely taken up by the department of civil engineering, the chemical and metallurgical laboratory, the physical and electrical engineering laboratory, the steam engineering laboratory, Williams Hall for mechanical engineering, &c., Saucon Hall for the English department, Christmas Hall, with drawing-rooms and the offices of the Y.M.C.A., the Sayre astronomical observatory, the Packer Memorial Church, the university library (1897), dormitories (1907) given by Andrew Carnegie, Drown Memorial Hall, a students' club, the college commons, and a gymnasium.
His administration of the University was marked by the introduction of the "preceptorial" system, by the provision of dormitories and college eating-halls for members of the lower classes, and by the development of the graduate school.
