The ruins of an ancient Jewish ritual bath have been found near Rome – the oldest such discovery outside of the biblical region of Israel and the surrounding area.

Rome and Ostia to this day are dotted with remnants of Jewish heritage: a menorah on the bas-relief of the first-century Arch of Titus; Jewish catacombs; sundry Roman-era inscriptions, and a synagogue at Ostia Antica.

As they worked, the team uncovered a smaller rectangular room with a wide set of steps leading down to a well. Archaeologists identified it as an ancient Jewish ritual bath, known as a mikveh, dating back at least 1,400 years.
