According to the stratigraphic study of its surfaces, this road was laid out after 480 BC and saw intensive use during the 5th century BC. On both sides of the road extended the cemetery, where a wealth of grave goods was found accompanying burials or cremations throughout all periods of its use. These include clay vessels of all types—some attributed to known ancient workshops—figurines of human and animal forms, glass and clay perfume containers, bronze mirrors, gold jewelry, coins, and other objects. Across the entire excavation area, numerous funerary markers (small columns, stelae, and marble vessels) were discovered, which had been erected above the graves. Several of these bore inscriptions revealing the names and origins of the deceased. In the second half of the 3rd century AD, following the destructive invasion of the Heruli in Athens, the site ceased to be systematically used as a cemetery, and most of it was occupied by a complex of pottery workshops. These workshops appear to have remained in operation during the 4th century AD, a period of prosperity for Athens. Based on the material found in and around the kilns, it is evident that production included vessels, household utensils, lamps, tiles, and antefixes. On the occasion of the construction of an underground parking station, a large-scale excavation was carried out in Kotzia Square between 1985 and 1988, covering an area of 7,000 square meters. A supplementary investigation was conducted in the entrance and exit areas of the station in 1998–1999. Following the completion of the excavations, it was decided to preserve the most representative section of the findings. Thus, an archaeological site was created, which was enclosed, conserved, highlighted, and opened to the public.
