There is evidence of a courthouse building constructed in Brunswick, Georgia some time before 1829, and while the ultimate fate of this building is unknown, it most likely burned down. Following this, court activities were held in rented spaces until 1884, when a wooden courthouse was constructed.[1] The building's construction coincided with a growth in activity of the Port of Brunswick, and several years later, in 1892, a new city hall building designed by Alfred Eichberg was constructed.[2] This city hall contained courtrooms that served the city court as well as the county court for Glynn County.[3] There is evidence that in 1897, plans were put forward to construct a new courthouse designed by Frank Pierce Milburn, but a failure by the city to secure a bond issue caused the project to die.[1]
During the 1970s energy crisis, the exterior of the building was covered by a façade to increase energy efficiency. Additional modifications to the building over the next several decades included the installation of sound boards for soundproofing and dropped ceilings.[6] In 1991, a new courthouse was built which partially replaced this building.[7] However, starting in the 1990s, the old courthouse building began to undergo a series of renovations that aimed at returning the building to its historic condition. Phase I of the renovations, which included stabilizing the structure and replacing the copperdome, cost approximately $1 million.[6] In 2001, the renovations entered into Phase II.[8] Phase II, which cost approximately $1.2 million,[6] included the installation of fire detection and prevention systems and bringing the building up to compliance with the Americans with Disabilities Act of 1990.[8] Following this, a Phase III (with a cost of between $1 million and $1.5 million) focused on interior renovations.[6] Following the Phase II renovations, the courthouse served as the meeting place for the county commission.[8]
As of 2019, due to a lack of space at the new facility, the Old Glynn County Courthouse houses the county's probate court.[7]
The building is surrounded by southern live oak trees covered with Spanish moss that partially obscure the building. According to one historian, "the effect of this building today is moody and nostalgic, recalling not the pure light of the Renaissance but a shadowy classical ruin, more emotionally poignant and appropriately Southern than any new structure."[10]
