Ring for admission to this landmark church which stands on the spot where Pope Gregory supposedly dispatched St Augustine to convert the British. It was originally the pope’s family home but in 575 he converted it into a monastery. It was rebuilt in the 17th century and given a baroque makeover a century later.
Inside, look out for the Cappella Salviati , a 16th-century chapel by Carlo Maderno, which contains a fresco of a Madonna with Child .
Outside, the Cappella di Sant’Andrea is the most interesting of three small chapels, with frescoes by Domenichino, Guido Reni and Giovanni Lanfranco.
