The Basilica Minore de San Sebastian or, more known as San Sebastian Church, is the seat of the Parish of San Sebastian and the National Shrine of Our Lady of Mt. Carmel. It is a fine example of the revival of Gothic architecture in the Philippines. It prides itself as the only all-steel basilica in Asia. The church is under the care of The Order of the Augustinian Recollects and is located at Legarda Street, Quiapo, Manila.
The Church of San Sebastian was raised to the status of a minor basilica by Pope Leo XIII on June 24, 1890. The following year, on August 15, 1891, the all-steel church of San Sebastian was inaugurated and blessed. The interior of the church displays groined vaults in the Gothic architecture style. The steel columns, walls and ceiling were painted to resemble marble and jasper by Filipino artist Lorenzo Rocha and his students. True to the Gothic revival spirit of the church are its confessionals, pulpit and altars as designed by Filipino artist Lorenzo Guerrero. He, with fellow artist Eulogio Garcia, carved the statues of holy men and women. Trompe l'oeil paintings were used to decorate the interiors of the church.
In addition, the church was listed among the 1998 World's Most Endangered Sites by the World Monuments Watch. On May 16, 2006, San Sebastian Church was included in the Tentative list of the World Heritage Site citing its architectural and historical heritage. The Basilica falls under criteria i, ii and iv will be included under category of cultural sites.
