Baroque architect Francesco Borromini died on this day in 1667. Renowned for his inventive architectural design and rivalry with Gian Lorenzo Bernini, Borromini’s Roman churches epitomize the High Baroque with their spectacular, theatrical, and organic designs, like those for San Carlo alle Quattro Fontane and Sant’Ivo. Other important projects include the Oratory of S. Filippo Neri, the Lateran Basilica, the Palazzo Barberini, and Sant’Agnese in Agone (after 1652) opposite Bernini’s Four Rivers Fountain (1651) in Piazza Navona.
