The churches of Santa Margherita and Santa Giulia are two religious buildings located in Noli, reachable from via XXV Aprile via a path. The two buildings lean against each other: the larger Santa Margherita to the west and the smaller Santa Giulia to the east. According to some, it was a single building dedicated first to Santa Giulia and then to Santa Margherita; the most probable hypothesis is that instead they were two leaning churches, of which Santa Giulia was built around the 11th century and Santa Margherita in the 13th-14th century.
The churches are located along an ancient path that connected Noli to Finale. Some scholars assume that these were built on the remains of an ancient pagan temple: there was in fact a Roman cinerary urn from the III or IV century, incorporated into the walls and used as a holy water stoup, which is now located in the council chamber of the Municipality of Noli. . Used until the seventeenth century, until the twentieth century they were a destination for pilgrimages on name days and Easter Monday.
The style is Romanesque. Unlike the other religious buildings of Noli, in local stone, the two churches are built with bricks mixed with black stone from Capo Noli. Bricks are used in the internal arches, in the hanging arches and in a frame under the roof. In both apses there are traces of the ceramic basins, similar to those of the main apse of San Paragorio. Today completely destroyed, the bell tower was placed to the west. Along the external walls there were two small windows from which it was possible to see in advance the arrival of the enemies.
The complex and especially the Church of Santa Giulia were seriously damaged during the Second World War.
