Mount Calvert is one of the most significant historical and archaeological sites in Prince George's County. Not only did it become Prince George's first county seat in 1696, but archaeologists have uncovered evidence of over 8,000 years of human culture!

Seasonally you can watch archaeologists uncover the past of American Indians, an early colonial town, and an 18th and 19th century tobacco plantation. Or you can walk through the museum's permanent exhibit A Confluence of Three Cultures to see what archaeologists have found. See how archaeology helps us understand our county's past.
