Welcome to Sant'Andrea al Quirinale, the Church of Saint Andrew on the Quirinal Hill, right here on Via del Quirinale. It is a small building, easy to walk past, and yet it is one of the most celebrated examples of Roman Baroque architecture in the city. It was built between 1658 and 1670 as the chapel of the Jesuit novitiate on the Quirinal, which is why older sources sometimes call it Sant'Andrea al Noviziato, Saint Andrew at the Novitiate. It stands opposite the long wing of the Palazzo del Quirinale known as the Manica Lunga. The design is by Gian Lorenzo Bernini, working with Giovanni de' Rossi, and it was commissioned by Cardinal Camillo Pamphilj with the approval of Pope Alexander the Seventh. Bernini considered this church his best work, precisely because architecture, sculpture and painting meet here in a balance he felt he never surpassed. Before you go in, look at how the church greets the street. It sits back from the road, framed by low curved walls. A short walk away, Borromini's San Carlo alle Quattro Fontane presses right up against the pavement. Two rival geniuses, two very different ways of saying hello.
