The Shrine of Mary, Queen of Peace, Our Lady of EDSA, or more popularly, the EDSA Shrine is a small church of the Roman Catholic Archdiocese of Manila located at the intersection of Ortigas Avenue and Epifanio de los Santos Avenue (EDSA) in Barangay Ugong Norte, Quezon City. The shrine is also called the Archdiocesan Shrine of Mary, Queen of Peace or Mary, Queen of Peace Quasi-Parish, although these names are seldom used. Built in 1989 originally to commemorate the memories of the People Power Revolution and its peaceful outcome, the shrine stands on the site of two peaceful demonstrations that toppled Philippine presidents Ferdinand Marcos (the People Power Revolution or EDSA I) and Joseph Estrada (the EDSA Revolution of 2001 or EDSA II).
