Romanesque church with a single nave, covered by a barrel vault and ending in the east with a square-plan presbytery. The central nave is flanked by two pairs of square lateral chapels. Notable are the dentil elements arranged in a frieze under the roof eaves. Parts of the original Romanesque structure are preserved in the western sector of the nave, distinguishable by its regular masonry. The later elements and the apse were built in 1819. The entrance door opens in the west façade through a semicircular arch. On the southwest corner stands a square bell tower ending in a terrace. The dedication to Saint Stephen is documented in Tuixent as early as 963, in a donation from Count Borrell II of an allodial estate to the village.
