Mill Hill Historic Park in Norwalk is a living history museum composed of three buildings: the circa 1740 Governor Thomas Fitch IV "law office", the circa 1826 Downtown District Schoolhouse, and the 1835 Norwalk Town Hall; as well as a historic cemetery originally called the Town House Hill Cemetery. The museum is also known as the Mill Hill Historical Complex in some references and the sign at the parking lot reads Norwalk Mill Hill Museum.
Enjoy a walk through the grounds as you soak up some early American history. If you visit during operating hours, there is an admission fee to enter the building, but there's no fee to visit the grounds (that's where the cache is).
I have permission for the hide and please respect the property as you track it down.
BYOP!
Congratulations to The Halloween Queen on the FTF!
