Excavation in the area of Eleonas Station, where the ancient demos of Lakiades was located, brought to light an impressive discovery: three foundation piers and parts of one of the arches of the ancient stone bridge over the Kifissos (Cephissus) river

The Iera Odos was the main road in antiquity. It started from the Holy Gate of the wall of Athens, in the area of Kerameikos, and ended in Elefsina, in the Sanctuary of Demeter and Persephone. The worship procession to Eleusis passed through the Iera Odos. Before entering the sanctuary, the procession of the faithful rested and regrouped in Pompeion. Along the ancient road there were gardens, fruit trees, rural sanctuaries, shrines, cemeteries, funerary monuments. The Iera Odos was also an important trade route that connected Athens with the Peloponnese and central Greece.

As part of the expansion of Line 3 of the Metropolitan Railway of Athens in the area of Egaleo, an excavation was carried out, which revealed part of the ancient Iera Odos (Sacred Way) and the remains of a cemetery on both sides.

About one kilometer east of the entrance to the Sanctuary of Demeter in Eleusis, at the point where the ancient Iera Odos (Sacred Way) met the riverbed of the Eleusinian Kifissos (Cephissus), an ancient bridge is preserved in an impressively fine state dated to the Hadrianic age.

In the middle of the way to Eleusis, the Iera Odos met the Sanctuary of Aphrodite (today in the area of Chaidari, shortly after the Monastery of Daphni). The sanctuary is well known from a reference by the Greek traveler Pausanias who identified it during his course to Eleusina. The Sanctuary was in use from the classical to the Roman period.
