Castle Hill
From Salem Links and Lore
Records on Castle Hill date back to 1636, when it was part of Derby Farm in South Salem. For a long period, an elegant summer home was situated on top of the hill. According to Fred Gannon's "Nicknames and Neighborhoods" the origin of the name is obscure. Colonists at one time had a watch tower on the summit as a precaution against attacks by Indians. Later, Salem merchants had summer homes on the hill, but in recent years, the ledge was blasted to make stones for streets.
