SAN ANTONIO, TEXAS—Achaeologists are excavating at the site of the Alamo in an effort to locate the 18th-century mission’s original south and western adobe walls, according to Texas Public Radio. The dig is part of a planned eight-year effort the redevelop the World Heritage site. “To re-imagine the Alamo we first have to rediscover it,” says city archaeologist Kay Hindes. “So the work that we’re doing here is to try to determine the exact compound walls and to confirm those in the ground.” The team is using archival maps and leads provided by a 1970s-era excavation at the site to guide their work. In addition to the mission's original walls, they expect to find artifacts left behind by both the Catholic priests and Native Americans who lived at the site.
