Our Lady of Mt. Carmel Church was built by Hispanic settlers in the Trujillo Creek area, west of Aguilar, in the late 1800's. Land was donated by Jose Maria and Juan Bautista Vigil. Celedon Vigil made 3000 adobes for the church and was assisted by many volunteers in erecting the building. A bell was donated by Michele Passarelli who was married to Carmelite A.Quintana. It was first a mission of St. Anthony's Church in Aguilar.

St. Anthony of Padua Catholic Church was first known as the "Parroqula of San Antonio" built in 1875. The land was donated by Francisco Gonzales and his wife, Maria Donaciana of the settlement then known as San Antonio. It was facing east towards the Apishapa River. A pot bellied stove in the center was the only source of heat in the winter. Originally the cemetery was located next to the church, which was a common practice. But by 1889 the cemetery was relocated on a rise on the east side of the river. In the early 1920's plans were made to erect a larger church. The stone for the new building was cut from the area surrounding the Empire Mine. Shortly after completion, the building was condemned because the foundation was not solid enough. The old adobe church was put to use once again.

The current church was competed in 1922. Each of the beautiful stained glass windows was donated by a particular family. The St. James Church in Augusta was torn down in 1949 and the adobes were used to build the rectory. In 1964, permission was granted to build a vestibule, designed by Father W. F. Ferrell, and men of the parish found & chiseled the stone to match the original building.

Community Presbyterian Church of Aguilar was erected in 1906 as an American Methodist Church. The church served as a hub of many community activities. In 1944 the church was initiated into the family of Presbyterian Churches. Although membership has declined, it has remained an integral part of the community.

St. Joseph Church of Gulnare was built when the Church of Saints Peter & Paul was dismantled in the mining camp of Delagua around 1956. With the close of the mine, the valley became desolate and to perpetuate the memory of the church in Delagua where so many people had been baptized and worshipped, the stones were used to build a new church for the San Jose district of Gulnare.
