What Is the Oldest Building in Ancient Greece?

The ancient civilization of Greece is renowned for its remarkable architectural achievements. From towering temples to grand amphitheaters, the Greeks were masters of construction.

But what is the oldest building in Ancient Greece? Let’s explore this question and discover the history behind it.

The Heraion of Argos

One of the oldest buildings in Ancient Greece is the Heraion of Argos. This ancient temple is dedicated to Hera, the queen of the gods and wife of Zeus. The temple is located in Argos, a city in the northeastern part of the Peloponnese peninsula.


The Heraion of Argos dates back to around 700 BCE, making it one of the oldest surviving temples in Greece. The temple was built on a hill overlooking the city and served as a center for religious worship and civic events.

Over time, various rulers and conquerors modified and expanded the temple complex. In 423 BCE, for example, Athens added a large stone altar to commemorate its victory over Sparta in the Peloponnesian War.

After falling into disrepair during Roman times, the Heraion was rediscovered by archaeologists in the 19th century. Excavations have revealed numerous artifacts and structures that shed light on ancient Greek life and culture.


The Heraion’s architecture reflects its long history and various modifications over time. The original temple consisted of a simple rectangular building with a wooden roof.

Later additions included a large courtyard surrounded by colonnades (covered walkways with columns). The altar added by Athens was particularly impressive, measuring over 12 meters long and adorned with intricate carvings depicting mythological scenes.


The Heraion of Argos is significant not only for its antiquity but also for its cultural and historical importance. As a center for religious worship, the temple played a vital role in ancient Greek life and society.

The temple’s dedication to Hera, the patron goddess of marriage and fertility, also reflects the importance of family and procreation in Greek culture. Additionally, the temple hosted various civic events and served as a gathering place for political assemblies.


In conclusion, the Heraion of Argos is one of the oldest surviving buildings in Ancient Greece. This remarkable temple complex reflects the long history and cultural significance of Greek architecture and society. Its impressive architecture and rich history continue to fascinate scholars and visitors alike.
