The museum occupies five rooms on the upper floor of Palazzo del Seminario.
One section is devoted to modern religious art.
It is closed for restoration (at January 2009).
It is described on the site of Musei Ecclesiastici Umbri.
[I think that the following are now in the Museum]
Circumcision of Christ (1560)
Madonna and Child with saints (1568)
✴the Madonna and Child in glory with musical angels; and
✴SS Sylvester, John the Baptist, John the Evangelist and Aloysius below.
The altarpiece was documented in the Duomo in 1872 and later moved into storage. It emerged in 1987 and was restored in 2009.
Agony in the Garden (ca. 1630)
This altarpiece by Francesco Cincinnato was moved from the church of Santa Maria del Cassero in 1841 to an altar in the Duomo that belonged (like the church) to the Confraternita del SS Sacramento.

This panel, which depicts a miracle that happened when the relics of St Cassius were returned to Narni in 1679, is attributed to Girolamo Troppa.

This panel from the Baptismal Chapel in the Duomo is attributed to Agostino Masucci.
