The National Shrine of Our Lady of Fatima is a church and national shrine under the Diocese of Malolos. It serves as the Philippine apostolate of Our Lady of Fatima, whose devotion originated in Fátima, Portugal and is formally recognized by the Catholic Church in the Philippines.

The Our Lady of the Abandoned Church, completed in 1572, is the seat of Nuestra Señora de los Desamparados, the Patron Saint of Marikina. The church is constructed in Baroque style characterized by a heavily fortified facade, large-scale ceiling paintings, a round pediment for the bell-tower and the lavish blending of painting and architecture.

The San Felipe Neri Church of Mandaluyong was established in 1863 and played a significant role as a relay station for propagating the Katipunan during the 1896 to 1897 Revolution.

Pasig Cathedral or Immaculate Conception Cathedral Parish is one of the oldest structures in Pasig City being founded in 1573 by the Augustinian missionaries. The church has historical importance as it served as the British military headquarters during the brief British occupation of Manila in 1762 to 1764. The British used the church’s belfry as a watchtower against the Spanish defenders. The parish was elevated into a cathedral in 2003.
