Known as "Arrowston," this house sits on 6.3 acres in Piqua, about 30 miles north of Dayton, Ohio.
Why it's on the register: Built in 1887, it's a wonderful example of Colonial Revival architecture and is also noted for its landscape architecture. "The family that built it, the Boal family, started Favorite Stove & Range Company," says Stephen Payne, sales associate with Irongate Realtors in Dayton, Ohio.
"Obviously, substantial money went into (it)," he says. "It was the crown jewel of Piqua -- still is."
What makes it memorable: "It's like walking into a museum," says Payne.
A spiral staircase rises from the center hall -- itself a chessboard of black and white Italian marble. Moldings are "massive," and the ceiling "probably hits 13 feet," he says.
The windows "are pretty much floor-to-ceiling in a lot of the rooms," he says. And the solarium, tucked behind the main staircase, "faces north toward Echo Lake."
The walnut-paneled library has herringbone oak floors and a working fireplace, plus a recessed "bourbon closet" plumbed for water, Payne says.
An industrial-grade kitchen is set up "to entertain large groups," he says.
The oversized pool has a pool house with changing rooms and a three-bedroom apartment. There's also a two-bedroom cottage on the property, plus a six-car garage and a stable.
