Chiesa di Sant'Antonio Abate

The church was built in the 15th century and dedicated to Saint Anthony the Abbot. A marble plaque, embedded in the first column on the right, commemorates this event.

The church was commissioned by the lords of Illasi for the workers who cultivated their lands near Costeggiola.

Throughout the 1500s, several requests were made by the inhabitants of Costeggiola for a stable celebration of Mass and the construction of a house for the chaplain.

Over the years, the church has been enlarged and restored multiple times, with three significant interventions: an enlargement in 1663, a renovation in 1707, and the most radical one in 1938, during which it was expanded towards the entrance with the construction of an additional bay. Externally, the building features a facade with protrusions facing west.

In 1864, a new cemetery was established separate from the church, and in 1909, the baptismal font was obtained, giving a degree of autonomy from Castelcerino, which remained the reference parish until 1929. Finally, on June 25, 1929, the bishop's decree was issued, officially establishing Costeggiola as a parish.
