Officials said that the remains, found in the Monks Burial Room and Nave in the Alamo Church, were thought to be that of an adult, an infant, and a young adult. None of the bodies have been moved, and further excavations are on hold.

The excavations were being done in conjunction with the installation of moisture monitoring equipment and a project to document the foundations of the place.

It wasn't the first time that archaeologists had found human remains at the site, according to the Alamo Mission Archaeology Advisory Committee. Records show other such finds in 1937, 1989, 1995, and earlier this year.

The Mision San Antonio de Valero was built by Catholic missionaries in 1718 near what is now San Antonio. Many missionaries and those they wanted to convert to Christianity lived at the mission through the years.

During the fight for Texas independence, the Alamo was the site of what amounted to a massacre. The March 6, 1836, battle pitted a couple hundred Texians and supporters (including William Travis, Davy Crockett, and Jim Bowie) against more than a thousand Mexican soldiers. The Mexican victory that day morphed into a rallying cry for Americans who wanted to "Remember the Alamo."
