The chiesa di Santa Maria Assunta in Castellare si trova nella frazione di Castellare – Pescia

A chapel dedicated to Santa Maria del Castellare is mentioned in the 1260 tax registry (estimo) of Lucchese churches; at the time, it was dependent on the Pieve of San Piero in Campo and stood near the site of the current building. In 1562, a new structure was built on the spot where the Chapel of the Crucifix stands today, thanks to the contributions of the Baldaccini, Minghi, Orsi, and Rosellini families. The Torrigiani family of Lucca donated a 17th-century crucifix to the small church—the work of a German sculptor active in Florence—as well as a carved wooden altar in the Baroque style, a fine example of 17th-century Lucchese craftsmanship. The church is noted as a rectory (rettoria) within the papal brief that established the Diocese of Pescia on March 17, 1727. In 1864, the small temple was partially demolished to make way for the construction of the current Neoclassical building, designed by Carlo Cervelli of Lucca. The first stone was laid on February 5, 1865, and the temple was consecrated by Giovanni Benini, Bishop of Pescia. The church houses works by Antonio Franchi and Benedetto Orsi.
