The Story
The Basilica of Sts. Cosmas and Damian stands at the edge of the Roman Forum, the first Christian church established in the heart of ancient pagan Rome. Founded by Pope Felix IV around the year 527 within halls of the imperial Forum of Peace, it honors the twin physician-martyrs whose names are spoken at every Mass celebrated with the Roman Canon. According to tradition, Cosmas and Damian were brothers from the region of Syria who practiced medicine without accepting payment — earning the Greek title anargyroi, 'the moneyless ones' — and won many to Christ through their charity. Tradition holds that they were martyred during the persecution of Diocletian around the turn of the fourth century and buried at Cyrrhus in Syria, where a basilica rose over their tomb. Their veneration spread rapidly through both East and West. Pope Felix IV's Roman basilica became a center of their cult in the West, and portions of relics venerated as theirs are kept there according to tradition. The church's sixth-century apse mosaic — Cosmas and Damian presented to Christ by Peter and Paul against a deep blue heaven — is among the most celebrated works of early Christian art in Rome, and its imagery shaped Roman church mosaics for centuries. The two martyrs are named in the Roman Canon of the Mass and honored as patrons of physicians, surgeons, and pharmacists. Pilgrims visit the basilica, now served by the Franciscan Third Order Regular, to venerate the saints, admire the mosaic, and pray for the sick and for all who care for them; their feast is celebrated on September 26.

Best Time to Visit
Best Overall
Apr-Jun & Sep-Oct
Comfortable weather and fewer peak-season crowds.
Peak Periods
Major feast days, school holidays, summer weekends, and organized diocesan pilgrimages can bring larger crowds. Book lodging and transportation earlier if your dates overlap a major celebration.
For a Quieter Pilgrimage
Choose a weekday outside the busiest holiday period and arrive early in the day.

Getting There From the United States
Best Gateway: Rome Fiumicino (FCO)
For most pilgrims traveling from the United States, Rome Fiumicino (FCO) is the most practical arrival point. Main U.S. gateway for Rome.
From the airport, continue toward Rome by the most practical combination of rail, bus, rental car, taxi, or pre-arranged transfer. For remote shrines, a private transfer or rental car is often simpler than piecing together local connections.
Typical U.S. Routing
United States -> Rome Fiumicino (FCO) -> Rome -> Basilica of Sts. Cosmas and Damian
Our recommendation: Compare total travel time, not airfare alone. A slightly more expensive flight that removes a long ground transfer can make a pilgrimage much easier.
On the ground
Getting Around
A rental car is usually unnecessary for a visit centered on Basilica of Sts. Cosmas and Damian. Rome is best handled with walking, public transportation, and occasional taxis or rideshare services.
Use transit for longer city movements and walk the final approach when practical. Historic centers often have limited parking and traffic restrictions.
Good to Know: Allow extra time around major feast days, weekends, and large liturgies, when local streets and transit can be crowded.
Where to Stay
Choose lodging in the most walkable part of Rome, ideally within a short walk or simple transit ride of Basilica of Sts. Cosmas and Damian. That makes it easier to attend Mass and return for prayer without losing time in traffic.
Best For Pilgrims
- Historic-center lodging near the church or shrine
- Religious guesthouses when available
- Hotels near a major transit stop
- Accessible lodging if your group has mobility needs
Pilgrim Tip: Check the actual walking route, not just the map distance; old cities can include steep streets, stairs, or cobblestones.
Accessibility
The main worship and visitor areas at Basilica of Sts. Cosmas and Damian are generally manageable for most pilgrims, though historic thresholds, paving, or side chapels may still create barriers. Accessibility services and entrances can change, so verify current arrangements before traveling.
Pilgrim Tip: If mobility is a concern, choose lodging and transportation that minimize unnecessary walking.
