In the days after the former 13 colonies declared their independence from Britain 250 years ago, Watertown had a moment. The town outside Boston became the center of government in Massachusetts, and two historic firsts took place right near Watertown Square. However, these occasions got lost in the ether somewhere between George Washington and George H.W. Bush.

In 17th century Watertown, Zachariah Smith fled charges of unlawful relations with neighbor Ruth Sawtell. The ensuing repercussions of his subsequent murder contributed to the outbreak of King Philip’s War. Three years later, an assignation with another neighbor made Ruth Sawtell a repeat offender, and the scene of their crime was the “Great Rock” in Rock Meadow.
