Heights of Guan

The Heights of Guan is a historical name given to a series of hills extending in a ridge along western Long Island in New York State.

The ridge extends in an east-northeast direction across the modern-day New York City boroughs of Brooklyn and Queens, with hills varying in height from 100 to 150 feet (30 to 46 m).

The Heights of Guan played a strategic role during the Battle of Brooklyn, early in the American Revolutionary War.

The ridge formed a natural defensive line against an attacking force from the south due to the steepness of the southern slope and the heavily wooded terrain covered in dense brush.

Roads were improved, however, and with urban sprawl after the mid-19th century various railroads crossed the Heights including the South Brooklyn Railway.
