The Church of Ordem Terceira do Carmo has a tour that covers the great work of Ordem Terceira do Carmo throughout the ages. The emblematic Carmo Church, a Baroque-Rococo national monument, shows secular religious art on its altars. Unknown to the inhabitants of Porto until recently, the mysterious Casa Escondida, the narrowest house in the city, reveals to us some secrets that have stayed there for centuries. The Catacombs have a unique exhibition of Ordem do Carmo’s Silverware, which glorify the Portuguese silversmithing. The Sacristy, where the priest vestments and liturgical implements are kept, its decoration is like an extension of the Church.
