Significant historic buildings in Collington
The southern segment of Maryland Route 197 is known as Collington Road.
James Mullican was appointed as the first overseer of roads in the Colony of Maryland, appointed in April 1696. Governor's Bridge over the Patuxent River was built by Governor Samuel Ogle in the mid-18th century to travel between his mansion in Collington and the state capital in Annapolis.
The Baltimore & Potomac Railroad Company had a passenger and freight station eponymously named Collington on the Pope's Creek spur of its Southern Maryland Line, 4 miles south of Bowie Station.  Today, a 5200 foot long railroad siding is all that remains of this stop although the spur is still in use. It is located at mile post 3.0 on the spur just south of where the spur crosses under Maryland Route 450 near Maryland Route 197.
Collington is known for its fine sandy loam soil on the surface making the area exceptional for agriculture. In the early 20th century almost 85% of the area was under cultivation for corn, wheat and tobacco with the remainder consisting of hardwood forest.
Below the topsoil lies layers of yellowish brown sandy clay and clay down to 48 inches.
