The Church of Saint Joseph of Maipo is erected on a rectangular floor plan rectangular of a single nave, its wall are made of adobe and structured on over pilasters and buttresses made with the same material. It was created on December 20, 1798 and its construction ended in 1800.
Many years later, between 1876 and 1877, under the management of the vicar Rafael Eyzaguirre several works were performed, among them the construction of the second Sacristy can be highlighted, as well as the three doors in the Sacristy and the High Altar was taken away brought from the Monastery of the Clare Nuns of Santiago; additionally, the High Choir was built and the ceiling was covered in wood, also, the windows were enlarged, which are of a Roman arch. For 1878, the construction of the main access is ordered, which is formed by Roman arches over brick masonry pillars.
Over the access the tower of the campanile in a neo-classic style is raised, whose design is attributed to the Italian architect Eduardo Pravasoli and which was seriously damaged with the 1906 earthquake. It was replaced with a new tower, which structured and covered in oak, ends in a spire with four curve mantles, crowned by a dome and the cross.
The roof is gabled and in the interior it is appreciated that the ceiling was stripped of the wood boards, leaving uncovered the structure formed by rustic “tijerales” or roof toppings. The Choir is also raised over two columns, all made of wood.
