His other known works are the elegant facade of the church of Trinità dei Pellegrini, with a concave profile, an 18th-century version of San Marcello al Corso by Carlo Fontana, and Borsani Claudio. Francesco de Sanctis (architect) Francesco De Sanctis (1679, Rome – 1731) was a late Baroque Italian architect, most notable for his design of the Spanish Steps in Rome in collaboration with Alessandro Specchi. These were built between 1723 and 1726 to celebrate
Spanish Steps of a more famous son, Gian Lorenzo Bernini, who is recently said to have collaborated on the decoration. The elder Bernini had been the pope's architect for the Acqua Vergine, since 1623. According to a legend, Pope Urban VIII had the fountain installed after he had been impressed by a boat brought here by a flood of the Tiber. In the piazza, at the corner on the right as one begins to climb the steps, is the house where English poet John Keats lived and died in 1821; it is now a museum dedicated to his memory, full of memorabilia
