The Baltimore City Circuit Courthouses are state judicial facilities located in downtown Baltimore, Maryland. They face each other in the 100 block of North Calvert Street, between East Lexington Street on the north and East Fayette Street on the south across from the Battle Monument Square (1815-1822), which held the original site of the first colonial era courthouse for Baltimore County (third county courthouse after previous locations / county seats in old Baltimore village on the Bush River and later Joppa) and Town, after moving the Baltimore County seat in 1767 to the burgeoning port town on the Patapsco River established in 1729-1730.
