On the west side of the complex was the Hotel-Dieu, the massive guest house for poor pilgrims, and the building of the Machicoulis (Named for its castle-like upper walls) which was a depot and kitchen for the chapter and the large Hotel-de-Dieu next to it, as well as a defensive structure if needed. Each of the five stories of the building had its own entrances. To the east of the cloister, and north of the transept of the cathedral, was the chapter house, the headquarters and residence hall for clergy, built in the last part of the 12th century. The oldest structure to the east is a Romanesque portal with sculpture on Rue Grasmement dating to the mid-12th century, which was formerly the entrance of the medieval hospital,
