Just an hour outside New York City lies a prim and proper Colonial compound steeped in history.

Originally built in 1940, the 20-acre Connecticut estate was once home to Richard Stiegler, a late shopping-center magnate who at one point had 51 properties across the country. While he died in 1967, his family has continued to steward the Westport spread for over 65 years. They’ve now decided to part ways with the home, though, listing it for the first time in six decades with a $15 million asking price.

Situated along a private lane and surrounded by protected open space, the abode offers the utmost privacy. The traditional main residence showcases intricate molding and dark wood flooring throughout, from the grand formal living and dining rooms to the more casual sitting rooms and breakfast nook, with practically all the spaces featuring stately fireplaces. The current decor leans a bit old-school, with floral drapery and decorative wallpaper, but the new owners could update it to their own tastes.

The primary bedroom, with a pink-striped walk-in closet and en suite, is found on the main floor, making the property ideal for those looking to age in place. Another bedroom is located here, as well, with the others found on the second and third floors, some with their own sitting areas. Two guest houses add private accommodations for friends and family, totaling seven bedrooms, six bathrooms, and one powder room across the structures.

Back at the main house, a tropical sitting room accented with green wood paneling leads to a glass-enclosed indoor pool and hot tub. Paired with a nearby screened-in porch, wet bar, and sauna, it’s a great place for entertaining. Downstairs, meanwhile, the finished basement could become a rec room, billiards room, or fitness center, with a large brick fireplace heating up the space.

While the indoor pool means you can splash around in any weather, when the sun’s out, you can enjoy the property’s grounds, which are equipped with a tennis court and formal gardens. Across the way sits Sherwood Island State Park, and views stretch to the Long Island Sound in the near distance. Andrew Whiteley and Wendy Ryan at Brown Harris Stevens hold the listing.
