The church of the Virgen del Castillo is originally a Gothic-Mudejar monument from the 14th century, which was profoundly reformed in the 16th century when the church was enlarged and the gable and the upper body of the tower were built. In the 17th and 18th centuries, several Baroque chapels were added: the chapel of the Santísimo Misterio de Aniñón, located on the south wall, opposite the main entrance to the church, and the chapel of Nuestra Señora del Rosario, located where the entrance to the church was originally located, and which was later moved to the south façade. Between 1985 and 2005, several phases of restoration work were carried out on the entire building.

Located at the exit to the old road to Calatayud is another of Aniñón’s points of interest: the arch-chapel of the town, with an ogival arch over which a two-storey body of popular character is developed.

It is worth mentioning the irregular urban layout of the town, where you can admire popular houses with white façades and two or three storeys. The Oil Museum is well worth a visit, where you can learn about the process of elaboration of the liquid gold in an original mill, as well as the Cooperative of Niño Jesús, where the rich production of the land of Aniñón is concentrated.
