Westerly Burying Ground dates to 1680. The oldest graves contain many of the town's earliest and most prominent families. Eight Revolutionary War veterans and fifteen Civil War veterans are also interred here. The site is significant for its large collection of three centuries of funerary art. One-third of its extant gravestones date from the eighteenth century; almost half date from the nineteenth century and only about twenty bear twentieth-century dates. Another distinguishing feature of Westerly Burying Ground is the number of individual mound tombs found here. Mound tombs at other burying grounds are typically larger, built to contain a number of bodies.
