In 1870, La Línea achieved the official status of a municipality[1] (it had belonged to San Roque up to then).

The city council answering to popular demand set up a committee to decide where a new church should be constructed.

Progress was slow and by 1879 pragmatic decisions needed to be made to create a working place of worship.

Notable features are the 17th-century reredos and the image of St. Mary made by the San Roque sculptor Luis Ortega Bru.

Inside the parish church of the Immaculate Conception there are images of Jesús del Gran Poder, and others belonging to four religious guilds.
