Why go

For the Milanese, Sant’Ambrogio is the city’s spiritual heart. The basilica was founded between 379 and 386 by Ambrose, the formidable bishop who baptised St Augustine and became Milan’s patron saint. The present building, rebuilt mainly in the 11th and 12th centuries, is the model of Lombard Romanesque architecture, and its calm brick facade comes as a contrast to the soaring Gothic of the Duomo.

You approach through a long colonnaded atrium, once a place of refuge, flanked by two bell towers of different ages: the shorter monks’ tower dates from the 9th century, while the taller canons’ tower was added in the 12th, a reminder of the long rivalry between the two communities that shared the church. Inside, the low, dim nave holds treasures that span more than 1,500 years, and Ambrose himself lies in the crypt beneath the altar.

What to see

  • The atrium. The arcaded courtyard in front of the church, with carved capitals.
  • The golden altar. A 9th-century altar covered in gold and silver panels by the goldsmith Wolvinius.
  • The ciborium and apse mosaic. A carved canopy over the altar and a glowing mosaic of Christ enthroned.
  • San Vittore in Ciel d’Oro. A chapel whose 5th-century mosaics include one of the earliest portraits of Ambrose.
  • The crypt. The remains of Ambrose and the martyrs Gervasius and Protasius.

Plan your visit

The basilica opens every day for worship. Tourist visits are welcome from Monday to Saturday between 10am and 12pm and between 2.30pm and 6pm, and on Sundays from 3pm to 5pm, provided no service is taking place. Entry is free and individual visitors need no ticket or booking; groups must book.

The San Vittore in Ciel d’Oro chapel and the treasury museum charge a small fee and are well worth it for the early mosaics. Allow 45 minutes to an hour for a visit.

The basilica is at its busiest around 7 December, the feast of Sant’Ambrogio and a city holiday, when Milan’s traditional Oh Bej! Oh Bej! Christmas fair is held nearby around the Castello Sforzesco.

Getting there

Sant’Ambrogio station on Metro lines M2 and M4 opens onto the square outside. The Last Supper is about ten minutes’ walk north-west and the Duomo about 20 minutes east.

Tips

Look for the bronze serpent on a column in the nave, a Byzantine piece that legend links to Moses, and the Roman sarcophagus beneath the pulpit. Dress respectfully and keep voices low.

Outside, look for the small Colonna del Diavolo in the square, a Roman column with two holes that tradition blames on a struggle between the devil and the saint. The basilica is also a working parish, so expect weddings and funerals at weekends; visit early in the afternoon if you want the church at its quietest.

Nearby

The Museo Nazionale della Scienza e della Tecnologia is two minutes’ walk away in a former monastery. The Catholic University occupies Bramante’s cloisters beside the basilica, and the Pusterla di Sant’Ambrogio, a rebuilt medieval gate, stands at the end of the square.
