The Seth Wetmore House is a residence built in the Center-Hall Colonial style in 1746 at 1066 Washington Street, Middletown, Connecticut.

Although Washington Street Extension passes close by on the southwest, the house is obscured from view by thickly planted trees.

No doubt one of the great local mansions of its day, it remains Middletown's best example of high style Georgian architecture.

the interior is of exceptional sophistication in its appointments; the northeast parlor alone is justly famous for the high quality of its decoration.

It displays in original condition a corner shell cupboard with sun-burst decoration; marbleized fluted pilasters at either side of the fireplace opening, and fine overmantel painting.
