This church is constructed with ashlar, brick and mud wall. It has Latin cross plant with lateral chapels. The greatest chapel and the four sections of the nave are covered with "lunetos", like the branches of the cruise. The lateral chapels have a vault of edge. There was a choir on the feet of the building, in the top of the church. The entrance has a reduced arch of brick and on it there is a steeple of brick too. It does not have a facade in the strict sense.
The building is of the second half of century XVIII but it was reconstructed after the war because it was seen seriously damaged. It was totally dismantled for the war. In its interior there are only baroque works made of plaster and rest of an altarpiece that was in the cruise.
Neighbors of Lierta celebrate their supervisory celebrations in honor to the Virgin of the Pilar the 12 of October.
