The lobby with its beautiful columns, today's building contains a museum and temple. Around it is a large archeological dig, where you can see remains of ruins of the Ancient Agora in Athens.
The Stoa of Attalos has a large significance in the teaching of classical architecture. This is because it was reconstructed exactly, bit by bit, exactly as the experts estimate that it looked in ancient times.
In ancient Greek architecture, a Stoa, is a building that contained a lobby, like a covered walkway, on one side there are columns that open up to the outside, while the other side has a wall with openings. The Stoai were used back then as public places, like for Agoras and markets, stores and galleries. The Stoai evolved to have to sides with columns, and some even had second floors.
At the beginning of the Stoai's history, it was built like a three or two-sided square, and held the inner space. The old Stoai were all built in the Dori style. Later, the Stoai were opened to new styles of design. Throughout history, when Stoai began including passages and two rows of columns, more and more Stoai included an ionic order in one row of columns and a row of columns in the Dori style.
During those days, on each of the two floors were 21 stores, and especially stood out the passage with the covered columns along the exterior of these stores.
In the year 267 BC part of the building was destroyed, after the invasion of the Herulim, an ancient German tribe, in the 3rd century.
Over the years, the remains of the Stoa were incorporated in a wall that was built in the city, a fact that will make its identification and rehabilitation in the modern era easier and faster.
Indeed, in 1950 the Greek government began the restoration of the Stoa, while excavating many artifacts, including toys, kitchen utensils, ancient coins and toys from ancient Greece, as well as architectural elements from ancient times, which are now displayed at the Stoa Museum.
This is how the Stoa was reconstructed in the 20th century and became the "Museum of Athens' Agora." Today many see it as the building that best exemplifies the Hellenistic period in Greece.
The Stoa is 115 by 20 meters. It has two floors, with two porches on each floor. The Stoa's columns are designed in two classical arches: the front pillars are of the Dorian order and the inner columns are in fine order.
Each floor of the Stoa has 21 rooms, with openings to the lobby and windows on the back.
We assume that the current structure is a fairly accurate reconstruction of the original structure and this in itself is very impressive. A small part of the original remains are incorporated in the reconstruction. The knowledge of the reconstruction itself comes from studies by expert archaeologists who have studied the original structure from 138 BC.
