 The choir has a magnificent giant candleholder with seven lamps sprouting from the mouth of seven rolled-up snakes.Above the main altar, inserting into the ceiling, is a gigantic jasper crucifix of 4.2 m, flanked by two kneeling angels, made by the School of Mafra.The cupola over the crossing was also inspired by the cupola of Sant'Agnese in Agone (by the Roman Baroque architect Francesco Borromini).
