The Chapter Hall of the Saint Helen Collegiate is the original nucleus of the museum. It was the last structure in the church complex to be built in the 1860s.
It was the meeting place where the canons deliberated on matters regarding the College itself and the administration of the church and it is still used on certain important occasions.
The walls are decorated with the coat of arms of Provosts and canons, and among the exhibits is a bust of patriot Vincenzo Borg, known as Brared, sculptured in limestone by Salvatore Psaila – the same artist who was commissioned by Borg to sculpture in wood the processional statue of Saint Helena.
Among other exhibis it houses Virginio Monti’s original bozzetti for the fresco cycle in the basilica dome and vaults.
