Founded in San Antonio, Texas in 1731, Mission San Juan Capistrano, located 12 miles south of the Alamo, is one of the 5 Spanish Colonial Mission churches constructed there during the 18th century.
The Mission chapel, although intact, was in serious jeopardy of eventual collapse due to unstable soils that were causing massive cracking in its thick load-bearing walls. The problems were especially acute at San Juan’s principal façade including its belfry. Earlier attempts to correct structural settling problems, including the addition of non-historic buttresses, had exacerbated rather than corrected structural problems.
The restoration architects designed an ingenious structural solution which required digging and pouring a massive grade beam under San Juan’s existing walls, and further supporting the beam on 30 steel reinforced concrete piers at the building’s perimeter. Once the buildings settlement problems were arrested it was meticulously replastered inside and out. Interior renovations included adding a devotional altar and wrought iron and carved wood screen at the rear of the chapel.
For nearly 300 years San Antonio’s missions, with the exception of the Alamo, have continued to function as active parishes and have served and shaped the local community. They are meaningful and valued spiritual places and are still relevant as centers of community and local identity. Mission San Juan, preserved for a much longer posterity, has national and international significance as a symbol of a Spanish Colonial past firmly rooted on the soil of North America.
