Architecture of the California missions

Architecture of the California missions

Overview
The architecture of the California missions was influenced by several factors, those being the limitations in the construction materials that were on hand, an overall lack of skilled labor, and a desire on the part of the founding priests to emulate notable structures in their Spanish homeland. And while no two mission complexes are alike, they all employed the same basic building style.

The founding of a mission followed longstanding rules and procedures; the paperwork involved required months, sometimes years of correspondence, and demanded the attention of virtually every level of the bureaucracy.

Some fanciful accounts regarding the construction of the missions claimed that underground tunnels were incorporated into the design, to be used as a means of emergency egress in the event of attack; however, no historical evidence (written or physical) has ever been uncovered to support these wild assertions.

Building materials


The scarcity of imported materials, together with a lack of skilled laborers, compelled the Fathers to employ simple building materials and methods in the construction of mission structures. Since importing the quantity of materials necessary for a large mission complex was impossible, the padres had to gather the materials they needed from the land around them. Five (5) basic materials were used in constructing the permanent mission structures: adobe, timber, stone, brick, and tile. Adobe
Adobe

The mixture was compressed into the wooden formas, which were arranged in rows, and leveled by hand to the top of the frame. From time to time, a worker would leave an imprint of his hand or foot on the surface of a wet brick, or perhaps a literate workman would inscribe his name and the date on the face. When the forms were filled, the bricks were left in the sun to dry. Great care was taken to expose the bricks on all sides, in order to ensure uniform drying and prevent cracking. Once dry, the bricks were stacked in rows to await their use. California adobes measured , were thick, and weighed , making them convenient to carry and easy to handle during the construction process.

In addition to the domes, vaults, and arches, and the Roman building methods used to create them, the missions inherited several architectural features from mother Spain. One of the most important design elements of a mission was its church belfry

, of which there were four distinct types: the basic belfry, the espadaña, the campanile, and the campanario. The basic belfry was merely a bell hanging from a beam which was supported by two upright posts. The belfry usually stood just to one side of the main entrance to the church. The second type, the espadaña, was a raised gable at the end of a church building, usually curved and decorated; it did not always contain bells, however, but was sometimes added to the building simply to give it a more impressive facade. The campanile, probably the most well-known bell support, was a large tower which held one or more bells; these were usually domed structures, and some even had lanterns atop them. The final method for hanging bells is the campanario, which consists of a wall with openings for the bells. Most walls were attached to the sanctuary building, save for the one at the Pala Asistencia
Mission San Antonio de Pala
The San Antonio de Pala Asistencia was founded on June 13, 1816 in what is today the Pala Indian Reservation located in San Diego County as an asistencia to Mission San Luis Rey de Francia, upstream from the mission on the San Luis Rey River.
