San Marco Evangelista al Campidoglio, Rome

In 336, Pope Mark built a church devoted to one of the Evangelists, his patron saint, St. Mark, in a place called ad Pallacinas. The church is thus recorded as Titulus Marci in the 499 synod of Pope Symmachus. At that time it became one of the stational churches of the city (Monday of the third week in Lent).

After a restoration in 792 by Pope Adrian I, the church was rebuilt by Pope Gregory IV in 833. Besides the addition of a Romanesque bell tower in 1154, the major change in the architecture of the church was ordered by Pope Paul II in 1465–70, when the façade of the church was restyled according to the Renaissance taste with a portico and loggia, using marbles taken from the Colosseum and the Theatre of Marcellus. The façade is attributed to Leon Battista Alberti. Paul II being a Venetian by birth, assigned the church to the Venetian people living in Rome.

The last major reworking of the basilica was started in 1654-57 and completed by Cardinal Angelo Maria Quirini in 1735–50. With these restorations, the church received its current Baroque decoration.

Madama Lucrezia is one of the "talking statues" of Rome, and is located next to the basilica entrance. It was once the bust of a statue of the goddess Isis, to whom a temple was dedicated in Rome not far from its current location.

The floor of the church is below the ground level of the Renaissance period, and therefore steps lead down to the interior. The church retains its ancient basilica format, with a raised sanctuary. The inside of the church is clearly Baroque. However, the basilica shows noteworthy elements of all her earlier history:

• the apse mosaics, dating to Pope Gregory IV (827-844), show the Pope, with the squared halo of a living person, offering a model of the church to Christ, in the presence of Mark the Evangelist, Pope Saint Mark and other saints;
• the wooden ceiling, with the emblem of Pope Paul II (1464-1471), is one of only two original 15th-century wooden ceilings in Rome, together with the one at Santa Maria Maggiore;
• Cardinal Angelo Maria Quirini (Cardinal Priest of S. Marco 1728–1743) restored the Choir, renewed the pavement of the Chapel of the Sacrament, and rebuilt the high altar.[1]
• the tomb of Leonardo Pesaro of Venice, aged 16, by Antonio Canova (1796).[2]

In the portico are several early Christian grave stones, as well as the gravestone of Vannozza dei Cattanei, the mistress of Cardinal Rodrigo Borgia.
