In 1734 the project is ready, in 1735 the works already proceed quickly, but soon the first difficulties are known: the building area on which the foundations rest is too deep: indeed it reaches about 15 meters (49 ft).

Then the new architect, Mauro Manieri, called directly from Lecce with Simone brothers, takes over the task of completing the work: we are already in 1742.

The original project the monastic complex by Valentino substantially reflects the current structure with the Church at the center and the spatial organization of the Monastery around it.

About a hundred years later the nuns will finally decide to build the Church to give prestige and to finish the monastic complex.

In total decay, in 1993 it is restored and on May 14, 1998, the provincial library, located inside it, is inaugurated in the presence of the Italian Prime Minister, Romano Prodi.

The Provincial Library "Tommaso Stigliani" founded in 1933, with its location in via Don Minzoni, then in via San Rocco, later in Malvinni-Malvezzi palace in the Cathedral square and at the Capuchin convent, finds its final seat.
