The monastery church dedicated to the SS. Trinità in Annunziata (Holy Trinity) was built in 1760 by master masons Pietro and Giuseppe Buccolini, as designed by the architect Carlo Murena. It seems that it was built on the site of another church dedicated to Saint Cecilia.
The ambitious initial projects included a precious stucco decoration that was never made. Twelve years later in 1772, Murena had died and only the supporting structure of the church had been completed. The nuns, anxious to begin church functions, decided to suspend the works and still today the building preserves only its wall structure.
Religious functions were suppressed in 1860, and the former church of the Holy Trinity is now home to the second CIAC museum center (Italian Contemporary Art Center) and hosts, among the various works, the famous “Cosmic Calamity” by Gino De Dominicis (1947-1998).
It is a very large skeleton lying on its back – twenty-four meters long by four meters wide, which was exhibited for the first time at the Museum of Contemporary Art Magazin in Grenoble in 1990, and finally ended up in Foligno after a long international tour.
