[1] The seat of the Diocese of Boac,[1] the cathedral today is surrounded by its likewise centuries-old defensive walls, and was declared a Philippine Important Cultural Property (ICP) in 2018 by the national museum of the country.

[2][3] At present, the Cathedral houses the Sacred Heart Pastoral Center (Bishop's residence) as well as the Diocesan Shrine of Mahal na Birhen ng Biglang Awa within its compound.

This event led to the devotion to Mahal na Birhen ng Biglang Awa (Our Lady of Prompt Succor) as their patroness's new title.

[2] The historical marker installed at the cathedral states that a Boac parish priest named Saturnino Trinidad helped Colonel Maximo Abad surrender to the Americans under H.H.

[5] The Diocesan Shrine of Mahal na Birhen ng Biglang Awa was established on May 10, 2008 (the feast day of her canonical coronation) by then-Bishop of Boac Reynaldo Evangelista and Cardinal Ricardo Vidal, Archbishop of Cebu.
