The chapel's ruins were demolished in the late 1970s, leaving only a few remains on the site. The remains of the chapel, which include Nibbia's sarcophagus, are now found in a cordoned area in the car park of Evans Building. The ruins were given a facelift by the Archaeological Services Cooperative and the Grupp Arkeologiku Malti (Maltese Archeology Group) in 2002, but they have since fallen into a state of disrepair. These remains were scheduled as a Class B national monument by the Malta Environment and Planning Authority in 2008. Architecture The Nibbia Chapel was an octagonal building with a dome. The façade had a large portal with the main doorway, which was flanked by two sets of Doric pilasters on either side. The door had an architrave with a marble plaque, which was topped by a broken rounded pediment. The upper section had a central arched window between small clusters of pilasters and running scrolls, and it was separated from the lower half of the structure by a thin cornice. Another triangular pediment topped the building. Crypt The chapel had a vaulted underground crypt which served as an ossuary. Skeletal remains of patients who had died at the Sacra Infermeria were arranged in decorative patterns on the walls, and the crypt therefore became popularly known as the Chapel of Bones. The crypt had one altar, which had a Latin inscription lamenting the ephemerality of life and requesting prayers for the deceased. The exact location of the crypt has been lost, and it could have been either under the chapel itself or in the immediate vicinity. Although the chapel was destroyed during the World War II bombings, the crypt might still exist.
