According to tradition, this sanctuary was built on the old Gothic parish of Saint Julian when a picture of the Virgin was discovered after the city had been reconquered. The old hermitage, or church was not built before the XV century and it is thought that it was in the place of the current crossing and the Hallazgo chapel or the 'Capilla del Hallazgo'. In 1747 the old temple was demolished and the present one built between 1750 and 1776 by Bernardo Rippa, with important refurbishment work being carried out throughout the XX century.

It is a baroque temple, with a Latin cross floor and neoclassic façade, with an anagram of our Lady of Monserate (Ntra. Sra. de Monserrate).

Inside the Hallazgo chapel is the cave where it is said that the Virgin Mary appeared and above this, the old niche which is dedicated to the Christ of the Good Death (Cristo de la Buena Muerte). The niche of the Virgin of Monserrate, patron saint of the city is in the main altar.
