Bryan County is part of the Savannah, GA Metropolitan Statistical Area.
Bryan County is separated into two parts (North Bryan and South Bryan) due to the location of Fort Stewart in the middle of the county. The Bryan County Courthouse is listed on the National Register of Historic Places.
The colonial town of Hardwick, laid out in 1755, served as the initial county seat. In 1797, the Georgia General Assembly moved the county seat to Cross Roads near modern Richmond Hil. On November 18, 1814, the county seat was moved to Mansford on the Canoochee River.  In 1860, the seat was known as Eden. By the 1880s the county seat was known as Bryan. By 1895 it was in Clyde, which may have been the same location formerly known as Eden and Mansford. Clyde served as the seat to 1935; in 1937 Pembroke took on that role. The only remaining sign of Clyde is a cemetery on the Fort Stewart military reservation.
A triangular area in the northeast of Bryan County, from northwest of Pembroke to north of Richmond Hill, is located in the Lower Ogeechee River sub-basin of the Ogeechee River basin, as is the northern half of the remaining area in the county south of Richmond Hill. The northwestern portion of the county, from east of Daisy to Richmond Hill, is located in the Canoochee River sub-basin of the Ogeechee River basin. The rest of Bryan County is located in the Ogeechee Coastal sub-basin of the same Ogeechee River basin. 
Bryan County is unique in that it is totally divided by the military installation at Ft. Stewart. Pembroke is in more rural north Bryan, while Richmond Hill in south Bryan county is a suburb of Savannah. To travel between the two on public roads, it is necessary to leave the county.
