Getting There: A mere 14 miles from Athens, Eleusis is easily accessible by car, taxi or bus.

What to See: The archaeological site is open daily, except Monday, from 8:30 to 3:00 p.m. Admission: costs 500 drachmas, or about $1.50, and includes entry to the site’s wonderful hilltop museum. Treasures inside the museum include a magnificent caryatid that once helped support the roof of the Lesser Propylaea and two fifth-century B.C. masterworks—statues of the goddess Demeter and Persephone. The museum also has two helpful models of the sanctuary: one shows the temple as it looked in the sixth century B.C., the other as is appeared in the Roman period.
