Mission San Miguel was founded in 1797 by the Franciscan order. Today the mission remains in use. The San Simeon Earthquake of December 2003 caused extensive damage. Conservators and Engineers turned to Saint Astier® limes in their quest to restore the mission. Saint Astier® Natural Hydraulic Limes were extensively specified for reinforcement masonry and renders.

The Franciscan Church, Arizona
Restoration of the church dome in Tumacacori National Historic Park, Arizona. Originally built with adobe in 1821, the dome was badly damaged mainly due to the use of improper modern materials for maintenance and past restoration. Layers of impervious materials such as cement, acrylics, waterproofing, etc. were removed, revealing the original adobe structure. The dome was then covered with a minimum of five layers of NHL 5 and NHL 3.5, recreating the original dome with adequate protection.
