The chapel was built in the 19th century by Father José Pinto de Moura and consecrated in 1899. At the time of its construction, religious orders were prohibited in Portugal. Nevertheless, it was later handed over to the Franciscans in 1921. In 1926, as part of the political changes (including the New State, etc.), a Franciscan convent was established there.
The architectural style is described as eclectic (a blend of different styles). The church has an elongated floor plan with a main nave, a main chapel, and a sacristy. Inside, there are several religious images, including works by students of the sculptor Teixeira Lopes. The chapel is located at Rua dos Bragas 321, Porto.
The chapel belongs to the Franciscan convent "Convento Franciscano de Nossa Senhora dos Anjos." It is known for the practice of perpetual adoration of the Blessed Sacrament (“adoração perpétua do Santíssimo Sacramento”), meaning it offers a place where the Eucharist is venerated around the clock. The day of the “Porciúncula,” a Franciscan celebration in honor of Santa Maria dos Anjos, is particularly celebrated here. This celebration has its roots in the tradition of granting plenary absolution/indulgence on August 1st and 2nd.
