Église Saint-Houardon de Landerneau, Gothic church in Landerneau, France

The Église Saint-Houardon is a Gothic church with a Latin cross layout, three aisles, and a flat chevet, dominated by a two-level bell tower at the front. The walls are built from granite rubble stone with cement coating, and the floor is paved with granite and sandstone slabs.

The original church was built in the 16th century on the banks of the Elorn River, but was relocated and rebuilt between 1858 and 1861. The relocation and reconstruction were funded under Napoleon III.

The church keeps a painting of Saint Houardon sailing in a stone trough, a subject sailors prayed to; in the choir is Yan' Dargent's fresco of saints converging on Christ (1891-1893). The parish lost its seat on 1 September 2017, when 22 active bell towers from Saint-Thonan to Rosnoën were merged into one parish.

The bell tower with multiple bells is visible from outside and the stone cladding shows natural color variations that appear different depending on the light. Walking around the church allows you to see all the architectural details, including the cylindrical stair turret on the north side.

The church was dismantled and rebuilt in the town centre in 1858, a move paid for by Napoleon III. Its portal and tower were classified as monuments historiques on 4 August 1916. Inside, the choir holds a fresco by Yan' Dargent (1824-1899), Cortège des saints personnages convergeant vers le Christ glorieux, painted 1891-1893.
