Église Saint-Lucien de Montmille

Église Saint-Lucien is a Romanesque church built with a single nave, transept, and flat chevet that define its straightforward layout. The interior displays solid masonry and clear architectural divisions typical of Romanesque design from its building period.

The church began as a Benedictine priory in the early 10th century, though the stone structure visitors see today was built during the 11th century. The building received protected monument status in 1913 to ensure its preservation.

The church is dedicated to Saint Lucien, the patron saint of the Beauvaisis region, and his veneration remains deeply connected to local identity. Visitors stand in a place that has held religious meaning for local people across many centuries.

The church sits on a hilltop overlooking the Therain Valley and can be reached from several surrounding settlements. Visitors should note that the elevated location means walking uphill to reach the building from lower ground level.

The building contains a rare medieval crypt without supporting pillars, hidden beneath the main church floor. This underground chamber marks where two of the martyrs venerated here met their deaths in early Christian times.
