The Historical Significance of the Archaeological Area

The site on which the Duomo was built has been a place of religious worship since Roman times. The significance of the Archaeological Area lies in the fact that it contained signs that proved that the area was used for uninterrupted religious practice for nearly two millennia. There are few places in Europe that can boast such an unbroken spiritual tradition.

From Roman Milan to Christian Worship

Milan (which was called Mediolanum in Roman times) was a significant imperial city, being the capital of the Western Roman Empire in the 4th century CE. Archaeological evidence displays how the city evolved from Roman religious practices towards becoming a nucleus of early Christianity in Northern Italy.

The oldest Christian buildings on the site belong to the period of Emperor Constantine, who made Christianity legal across the Roman Empire under the Edict of Milan of 313 CE. This milestone in history did not only reshape Milan but reshaped the Western world as well, and proof of this process lies in the archaeological remains. 

A Timeline of Sacred Structures

The Archaeological Area uncovers several important buildings that were on the site prior to the construction of the present-day cathedral:

• Roman structures (1st-3rd centuries CE): Fragmentary evidence of the initial occupation of the site
• Basilica Vetus (4th century CE): One of Milan’s first Christian churches
• Basilica di Santa Tecla (5th century CE): A large early Christian basilica
• Baptistery of San Giovanni alle Fonti (late 4th century CE): The octagonal baptistery where Saint Ambrose baptized Saint Augustine in 387 CE
• Santa Maria Maggiore (9th century CE): Medieval church that preceded the current cathedral

Construction of the current Duomo was started in 1386 under the order of Gian Galeazzo Visconti, Duke of Milan, which replaced the earlier buildings. But instead of completely erasing the past, remnants of these old buildings were kept hidden under the new cathedral to be rediscovered centuries later.

Major Highlights of the Archaeological Area

1. Baptistery of San Giovanni alle Fonti

One of the most important buildings in the Archaeological Area is the Baptistery of San Giovanni alle Fonti. The octagonal baptistery was commissioned in the late 4th century by Saint Ambrose, the powerful Bishop of Milan. The octagonal shape – a shape representing resurrection and rebirth, later became the generic template for baptisteries across Europe for many centuries to come.

What is so special about this baptistery is its historical association with Saint Augustine, one of the most influential theologians of Christianity. Augustine was baptized here by Ambrose in 387 CE, an event that was a turning point in Christian history. Today, the original baptismal font where this event occurred can be viewed by visitors.

The baptistery has architectural features characteristic of late Roman and early Christian design, such as:

• Octagonal design with a central pool
• Remnants of marble decorations
• Evidence of early hydraulic systems that provided water
• Pieces of mosaic flooring revealing Christian symbolism

2. The Basilica di Santa Tecla

Another outstanding highlight is the remains of the Basilica di Santa Tecla, a large early Christian church constructed in the 5th century. Santa Tecla was Milan’s summer cathedral (with Santa Maria Maggiore being the winter cathedral) for several centuries before both were replaced by the current Duomo.

Excavations uncovered large parts of Santa Tecla’s foundations, demonstrating that it was a gigantic building for its era proving Milan’s significance as an early Christian city. Tourists can see:

• The basilica’s impressive ground plan
• Remnants of enormous columns that previously held up the roof
• Fragments of liturgical furniture
• Proof of architectural changes implemented over the centuries

3. Ancient Mosaic Floors

Along the Archaeological Area, tourists may see beautifully intact pieces of ancient mosaic flooring. The designs are in the form of geometric shapes and early Christian symbols characteristic of the 4th and 5th centuries. The fact that these sensitive art forms survived provides an insight into the artistic taste of early Christian Milanese.

The mosaics reflect several symbolic themes such as:

• Fish (an early Christian symbol representing Jesus)
• Crosses
• Geometric shapes characteristic of late Roman art traditions
• Plant and animal imagery with Christian meaning

4. Roman Architectural Features and Artifacts

The Archaeological Area also contains a series of Roman artifacts found in excavations. These artifacts give information about life in ancient Mediolanum and include:

• Fragments of pottery
• Coins that date back over several centuries
• Architectural features like column bases and capitals
• Inscribed stones bearing Latin inscriptions
• Pieces of Roman building materials and construction techniques

These artifacts provide context for Milan’s significance during Roman times and demonstrate how early Christian building traditions were shaped by Roman architectural styles.
