The church was built in the 15th century by the Duchy of Arcos, which had the dominion over the city of Los Palacios. The Ponce de León family felt a great devotion to the Virgen de las Nieves, patron saint of their city, so they dedicated the temple of Los Palacios to this Marian devotion. Inside, the organ stands out, built by Francisco de Ortiguez in 1747. In 2001, the palace sculptor and restorer Juan Manuel Martín rebuilt the old wooden monstrance from the seventeenth century, transforming it into a small temple that processions in the corpus, with an image of the Child Jesus. The church is in Baroque style with several neoclassical contributions. The highlight of the parish church is the main altarpiece, the work of the Flemish master painter Pablo Legot and dating from the seventeenth century (1631-36). The three canvases that make it up stand out: the central canvas representing "The Adoration of the Shepherds" and the side canvases with the two saints John, the Baptist and the Evangelist. The primitive altarpiece must have been modified in 1712 and definitively rebuilt in 1865.
