It has a single nave and a two-sided sloped roof. The Main Chappel is covered by a four-sided sloped roof. The belfry is attached to one of its sides, the whole building is surrounded by a wall.

Inside the temple it is worth mentioning its wooden coffered ceiling, a barroque bench and the wooden pulpit.
