On the south side of Race Lane, just west of Trotter's Lane, at 41°41′11″N70°26′12″W / 41.68639°N 70.43667°W / 41.68639; -70.43667 (Race Lane Marker), is a granite marker on the town line between Barnstable and Sandwich. The town line between these two towns was first laid out by the council of the Plymouth Colony in 1639, and has remained relatively stable since then. It is unknown when this rough granite marker was placed; on the street face it is marked with a B on the Barnstable side, and an S on the Sandwich side, with a carved vertical line between.[2] This marker was listed on the National Register of Historic Places in 1987 as "Town Boundary Marker".[1]
The Great Hill Road marker was in 1987 located a short way north of the road's junction with Cedar Street, but these streets no longer meet. Like the High Street marker, it was probably not placed until after the area was purchased in 1644. It is marked similarly to the Race Lane and High Street markers. It was listed on the National Register in 1987 as "Town Line Boundary Marker".[1]
