A stately approach marked by stone columns leads to a prominent area landmark property known as "Thunder Mill." The 1840 Federal main house sits atop gentlysloping park-like grounds overlooking a 3-acre pond and a waterfall thattumbles 15' into a flowing stream that is the source of the Neck River below.The 11-acre country estate offers extensive woods, gardens, rock walls andspecimen plantings. A footbridge over the river takes you east to the top of the falls and a century old grist mill that has been converted into a lovely guest house overlooking the pond and the woods beyond. There, wildlife abounds--fish, ibis, great blue herons, bald eagles, osprey, turkeys and even bluebirds. The property spans the towns of Guilford and Madison whose public schools rank in the Connecticut top 10.
