The Monastery of La Immaculada, now located on the outskirts of Valls, was founded in 1680, when four nuns from the Monastery of Jesús Maria in Barcelona, led by Basilisa de Pereire, took charge of the establishment. In 1684, construction began on the convent buildings next to the castle, a structure believed to have been built in the second half of the 12th century and later expanded, though no visible remains exist today. In 1683, the founder passed away and was buried in the monastery. Later, in 1761, the new church was inaugurated.

Between 1808 and 1811, during the Peninsular War, the nuns were forced to adapt their way of life and opened a school. In 1835, the monastery was converted into a military barracks, and later, its premises were occupied by the Hospital of Sant Roc, which was eventually relocated to the Capuchin convent. In 1846, the monastery regained its religious community, which remained until 1936, when the nuns were forced to flee, and the monastery was demolished. Notably, in 1860, Filomena Ferrer Galceran (Filomena de Santa Coloma) took her vows there; in 1894, she played a key role in founding the Monastery of Móra d’Ebre (Ribera d’Ebre), her hometown. After the Spanish Civil War, the community and monastery were reestablished until the property was ultimately sold. In 1952, the community relocated outside the city, to the Camí de la Verneda.
