What it feels like

Merrimac was settled in 1638 as part of Salisbury, later belonged to Amesbury, and became its own town in 1876. Through the 1800s it was known for building horse-drawn carriages, and the older houses around the center still show it.

Today it is one of the quieter towns in the Greater Newburyport Area: about 6,700 people on under 9 square miles, with Merrimac Square at the center and more open land the farther you go from it.
