The most notable neighborhoods/communities include Xaltocan, Ejidos de Tepepan, La Noria, Las Cruces, Ejidos de Xochimilco and San Gregorio Atlapulco. San Francisco Caltongo is one of the oldest neighborhoods of the borough. Xaltocán began as a ranch or hacienda that belonged to the indigenous caciques. It was later donated to the San Bernardino de Siena monastery. After the monastery was secularized, it became hacienda land again, but over time, parts were sold and it became the current area of Xochimilco. The church for this community was built in 1751 as the hacienda chapel. Originally, it was dedicated to Jesus, then Candlemas and finally the Virgin of the Sorrows (Virgen de los Dolores). It officially became a sanctuary in 1951, declared by the archbishop of Mexico. In 1964, Xaltocán became a parish and in 1976, this church became the official parish church. The main celebration of the church is to an image of the Virgin Mary, which is said to have miraculously appeared in the pen of a turkey kept by an old woman.
