In 1865, Warren Potter, a Rhode Island-based manufacturer, built this Italianate style mansion in the Dayville section of Killingly, Connecticut for his family. Potter was employed at the Sayles Woolen Mill in a manager role and clearly did well for himself to afford such a home. Characteristic of the style, the Potter mansion features bracketed eaves and window lintels and round-arched tripartite windows over the center entrance. At the entry, the original round-arched doorway with glazed surround has survived in good condition and is a showstopper!
