Archaeologists have discovered three burials at the historic Alamo site.

The finds were made during excavations of the Alamo monks' burial room and the nave of the church.

The Alamo is the site of one of the most famous battles in American history in which nearly 200 Alamo defenders were killed in March 1836 in a battle with Mexican forces during the fight for Texas independence from Mexico. The site in San Antonio was first established as a Spanish mission in 1744.

Experts were working around the Alamo church and the site’s Long Barrack to install moisture monitoring equipment and locate the foundations of the 300-year old structures when they made the discoveries.

“The remains encountered appear to be indicative of a teenage or young adult, infant, and large adult,” explained the Texas General Land Office and the Alamo Mission Archaeological Advisory Committee in a statement. “Upon discovery of the remains, the long-established human remains protocol was activated, the on-site tribal monitor was notified, and excavation of the particular site was halted.”

The Texas General Land Office told Fox News that while photos of the excavation project have been released, no pictures of the remains will be released out of respect for the deceased.

Remains were also found at the Alamo site in 1989 and 1995, according to the Texas General Land Office.
