The Basilica of San Sebastian is one of the 4 minor basilicas in the Archdiocese of Manila. It is said to be the only church in Asia built of steel. The architect decided to use steel to build the present structure because the church had been completely destroyed by an earthquake twice.
The basilica contains the National Shrine of Our Lady of Mount Carmel. Every year the feast of Our Lady is celebrated twice a year. The biggest feast is celebrated on January 31 with a traditional novena ending with a procession all along the parish streets. Her feast on July 16 is also celebrated with a novena but with a shorter religious procession.
San Sebastian was raised to a minor basilica in 1890. The basilica was consecrated in 1891.
