Santa Maria in Montesanto (Church of the Artists)

One of the famous 'twin churches' framing the southern entrance to Piazza del Popolo (with Santa Maria dei Miracoli opposite) — they appear identical from a distance but on closer inspection have different ground plans, designed to fit asymmetrical lots. Begun by Carlo Rainaldi (1662) and completed by Bernini (1675-79). Known as the 'Church of the Artists' because of its long association with Rome's creative community — the Sunday morning 'Mass of the Artists' draws actors, directors, painters, and musicians, and many funerals of major Italian cultural figures are held here. Limited opening hours.
