ALGIERS, ALGERIA—The AFP reports that excavation for a metro station in the Algerian capital has uncovered artifacts spanning a period of 2,000 years, including coins, weapons, a fifth-century public building from the ancient Roman port town of Icosium paved with mosaics, and a seventh-century Byzantine necropolis. The excavation, begun in 2009, has also revealed the remains of the Ottoman-era Es Sayida mosque, which was demolished in 1831 by the French colonial government. Revisions to the plans for the Martyrs Square metro station, set to open later this year, will incorporate an archaeological museum.
