We've seen some crazy celebrity houses before, but John Rich's massively extravagant Nashville mansion may be the coolest one yet.

The Big & Rich singer and songwriter dubs his 17,081-square-foot house Mt. Richmore, and it deserves every bit of such a stately name. Rich's 20-room mansion boasts five bedrooms, 10 bathrooms, an elevator and a private club that accounts for 4,000 square feet all by itself.

That private club features a fully loaded stage for musical performances, a fully stocked private bar and panoramic views of downtown Nashville. Rich's mansion also features a guitar-shaped pool that has been featured in numerous news stories and on TV shows ranging from Pickler & Ben to the Today Show.

Rich calls Mt. Richmore "the house that music built," but it's not just ostentatious for the sake of being showy. The private club serves as an event space where Rich hosts charity events, and as he tells the Today Show, "We've raised over a million dollars a year in this room for six years straight, for St. Jude, Vanderbilt Children's Hosptial, Wounded Warriors, the food bank and on and on and on."
