University of Georgia officials say they have halted expansion of a building on the Athens campus after construction workers discovered as many as 27 gravesites.

A statement released by the school Friday says workers discovered the remains on Nov. 17 while expanding Baldwin Hall. The building sits adjacent to the Old Athens Cemetery. It served as the official town cemetery in the 19th century.

UGA officials say the Georgia Bureau of Investigation and local coroner determined the remains were old. The State Archeologist's Office is researching an appropriate place to re-bury the remains.

Baldwin Hall was built in 1938. The university's statement says historical records indicated all remains at the site had been removed and transferred to another cemetery before the building's construction.
