On the ground floor there are some ancient halls which were intended
for professors and janitors and that are now home to the Medical Surgical
Society and to the Academy of Agriculture.
In the centre, in the eastern
side of the courtyard and in front of the entrance door, there is the
Chapel of Santa Maria dei Bulgari. Its name reminds that of a church which
stood in "curia Bulgari", near the houses of the famous jurist Bulgaro
(12th century).
The chapel preserves the remains of a cycle of frescoes
with "Stories of the Life of the Virgin" (1591-1594), by the Bolognese
painter Bartolomeo Cesi, who was one of the greatest interpreters of the
late-fifteenth-century Bolognese figurative culture. Unfortunately, the
frescoes were largely destroyed because of the air
raid that, on the 29th January 1944, had devastated the eastern side
of the building.
The chapel was rebuilt after the war by restoring the
stucco profiles that delimited the individual frescoes, according to a
mannerist system in which the panels approached each other like many framed
canvases.
On the high altar there is the altarpiece of the "Annunciation"
(1582) by the Flemish artist Denis Calvaert (around 1540 - 1619), founder
of a school where artists like Guido Reni and Francesco Albani will be
trained.
