Fodor's Expert Review Basílica da Santíssima Trindade

One of the largest Catholic churches in the world, seating some 8,500 worshipers, the Holy Trinity was consecrated in 2007 and raised to the state of basilica in 2012. Although it won prizes for engineering rather than architecture, its ample, curved form—designed by Greek architect Alexandros Tombazis—offers a pleasing contrast to its rather run-of-the-mill 1920s predecessor. Much of the iconography, including on the lavish main doors, was inspired by Byzantine and Orthodox motifs, and was produced by artists from Portugal and seven other countries. The Tall Cross crucifix outside the church is by the German artist Robert Schad.
