The Porta Mariae is a triumphal arc in Naga City commemorating the tercentenary of the devotion to Our Lady of Peñafrancia.

The arch, 18 metres wide, 4 metres deep and 11 metres high, is surmounted by a 10 feet tall brass image of Our Lady of Peñafrancia and two angels on each side. The main portal’s two small gates each accommodate three persons, while the central portal accommodates at least eight persons.

The arch was commissioned by the Archdiocese of Cáceres, and its construction was financed by the Peñafrancia Devotees of Metro Manila Foundation Inc. with General Salvador Mison as its director. It was designed by architect Gian Paolo P. Priela and completed under the direction of engineer Noriel L. Villar. The Porta Mariae was blessed and inaugurated by Archbishop Leonardo Legaspi on 9 September 2010.
