The Church of Saint Lazarus is currently located on Ejército Avenue with Gorbea Street and it is the second temple built, since the prior one was located on Avenida Bernardo O’Higgins, however its design is similar to the original one. The architectonic style of the work is rather eclectic, since it collects classic, romantic and Gothic ideas. In the exterior, it can be seen that the construction is divided in three entrances, the main one being in the center, accompanied with ornamental ceiling roses and semicircular arches, which go into the three interior naves and is finished off in the great central tower with the figure of Saint Lazarus.

The interior of the Church reveals what can be appreciated in its exterior. It has a floor layout of three naves, the central one being the highest, finished off by a large cannon vault. However, there is also certain eclecticism in its structure, since it is mixture of the Basilica-type floor layout with its large main half-sphere dome that is not located in the high altar but rather in the center of the temple. There a transept crosses with the cannon vault that only reaches the lateral naves. In the entrance there is a small atrium supported by columns that hold an upper floor where the large organ is located.

The division of the central nave with the lateral ones is done through large columns that hold semicircular arches, all the structure is of on-sight cement blocks. The walls are made with cement covered brick. The lateral naves are formed by a set of domes that are located between each dividing semicircular arch held by columns and that allow incorporating the devotional altars. The high altar is located in the apse of the central nave that finishes off in a clerestory and a gallery of semicircular arches containing decorative stained glass windows. They are linked through ogival pointed arches and their ribs meet in the central point forming a dome.
