Basilica of Notre-Dame du Port
The church, whose construction began in the 11th century and continues into the 12th and 13th centuries, was seriously damaged by the strong earthquakes that hit the region in 1477 and 1490, and underwent major alterations in the 19th century: engineer Ratoin rebuilt a new western bell tower in 1823-1827 and Aymon Gilbert Mallay led the second restoration campaign in 1843, notably rebuilding the transept crossing tower.
