The Church of San Sebastián is neoclassical in style and was built between 1780 and 1789 by Ventura Rodríguez. It has a Greek cross plan; the central space is occupied by a vaulted dome.
On the main altar of the Church of San Sebastián there is an altarpiece made of masonry and stucco, presided over by a painting of San Sebastián painted by Andrés García Ibáñez. It is accessed through a staircase, composed on both sides of a railing of marble balusters. The interior lighting is due to three circular windows located on the main façade. The walls of the baptismal chapel are decorated with paintings referring to the baptism of Christ dated 1932. At the foot of the temple is the high choir composed of wooden balusters.
The exterior façade has a tower at the head, consisting of a base, three bodies separated by simple moldings and dome-shaped roofs, and a clock that preserves the original machinery and was added in the year 1.897. The tower is topped by a weather vane with a copper ball and an iron cross. The exterior of the church is painted white, except for the base where the masonry factory can be seen.
