If you need a home that is literally fit for a king, River House in Potomac, Maryland, might be just what you're looking for.

River House in Potomac, Maryland, is an elegant mansion sitting on 15 acres of riverfront splendor. It was once the formal estate for the king and queen of Jordan, but the subsequent owner expanded the acreage by purchasing the surrounding parcels, giving the home an even greater sense of privacy and seclusion. This listing boasts nine bedrooms, nine full baths, and four half-baths, as well as many other necessities for a royal lifestyle, all for only $49,000,000.

Our tour of this amazing estate begins, as you might expect, at the front gate. This wrought-iron gate is set into impressive limestone walls with massive gas lanterns on either side. Once you enter the grounds, the 1/2-mile long driveway will take you through the English garden style landscaping to the guard's house, manager's house, guest house, garage, and, of course, the mansion itself.

The driveway ends at a large cobblestone motor court surrounded by a low wall made of the same french-milled limestone as the estate buildings. To the left of the entry, the cobblestone court leads around the house to the garage and guest house and the pool and grounds that slope down to the river. The pool offers a beautiful waterfall edge, integrated hot tub, and fountains. This striking pool and surrounding outdoor living area offer stunning views of the Potomac River.

Moving inside through the custom-made wrought iron front doors, the mansion has four floors. The vestibule opens into a reception hall with two-story ceilings and an imposing 24-foot limestone fireplace. The main level of the home also includes a formal dining room, a chef's kitchen, a living room, a family room, a library, a solarium, a spa lounge, a gym, and an office.

The second floor includes four bedrooms, each with an en-suite bathroom. The third floor is the master suite of the home, featuring an enormous bedroom with a private terrace that overlooks the grounds behind the house and the river beyond. The master suite also includes two spa bathrooms, an office with built-in bookcases and a beautiful marble fireplace, a dressing room, and a separate sitting room.

Traveling down to the lowest level, which by all rights should be the basement, we find yet another well-appointed floor of this home. This level features a wine cellar, a theater, and a club room. The lower level also accesses the backyard, due to the slope of the grounds, so you could walk from your theater, right out to your pool without any annoying stairs.

If this isn't enough space (or you plan to AirBNB the main house and live elsewhere on the property), there are three additional buildings. The guest house is connected to the main building by a covered walkway and features two bedrooms, a kitchen, a living room, and a dining room over the garage bays. The gatehouse sits directly behind the gate on the north end of the property. The manager's house is also on the north end of the property, separated from the main house by some distance. The manager's house features two staff bedrooms with their own private entrance, a formal reception room, a kitchen, a dining room, a conference room, and two offices.
