It stands front of an esplanade that currently holds the town's main square. The access faces south front of the sea, one block away from the coast. We know about the Rilán Chapel since 1658, when the missionaries described it as "a good Church, with lots of Spaniards and Indians". The current Temple belongs to the maturity of the Chilota School. It was built at the beginning of the 20th Century, the blessing of the first stone made on December 12th, 1907.

The building stands out for its vault. Its base is made of stone and its structure of coihue, cypress and canelo, while its interior coverage is of tepa. It is 38 yards long and 49 feet wide. The height of its central nave is 29 feet; its tower is 91 feet high.

It is one of the best-kept Churches. Its tower has two tambours of octagonal base covered with tiles. The portico presents pillars supported on bases, half-point depressed lancet arches, and the front is covered with tiles. The central nave has a vault of depressed half-arch and pillars with the shape of a cylindrical column. Its structure is of coihue and cypress, the tower of coihue and larch and is covered with larch, cypress and mañío.

The building has had alterations like tiles covered with galvanized iron (unknown year), the portico on concrete, the reduction of the tower's superior crown (spire) and periodical renovations of their paintings. The recovery works started during the year 1990.

It was declared National Historical Monument in 1971 and part of Mankind's Heritage before the UNESCO in December 2000.
