The Hôtel-Dieu of Carpentras was designed according to a checkerboard plan around a central main courtyard, a vestibule, and a grand staircase. Four wings at the four corners of the courtyard extend from the centerline of the entrance. The north-eastern U-shaped pavilion, organized around a square tower, was inaccessible to the public. It housed the chapel and the convent of the hospitable nuns. The northwest wing, also U-shaped on the courtyard, housed the administrative part of the hospital, its pharmacy, and the chaplain's accommodation. The large south wing accommodated incurable patients in the east and convalescents in the west and was bordered by a large vegetable garden that disappeared in the 19th century. Built between 1750 and 1769, the imposing Hôtel-Dieu was listed as a Historical Monument in 1862. It now houses a cultural center bringing together the municipal library and museums as well as the archives and the Inguimbertine library.
