VISALIA, Calif. — St. Charles Borromeo Church, which officially opened on February 2, is now the largest Catholic parish church in the United States. With a seating capacity of 3,148 and nearly an acre of interior space, it can accommodate nearly 1,000 more worshippers than the previous record holder: St. Matthew Church of Charlotte, North Carolina. The church stands out for its spaciousness and strong sight lines, which are meant to help generate the sense of community and inclusivity recommended by the Vatican II council on church design. Its large capacity will also allow a diminishing number of priests to serve a rapidly growing local population.
