A lottery winner is selling a massive California mountain estate for $26 million.

The sprawling estate sits on 845 acres near the town of Oak Glen and includes a 16,000-square-foot house with a sauna, a 17-seat movie theater, a three-story elevator, and a 4,000-square-foot garage.

Rick Knudsen won the $180 million California Mega Millions jackpot in 2014, quit his job, and bought the house - which was still under construction - for $5.5 million, according to The Wall Street Journal. He went on to buy an adjacent buffalo ranch and another swath of land, piecing together 845 acres in total. The estate also includes commercial property in the nearby town of Oak Glen, where he established a steakhouse and saloon.

The Eagle Crest Estate, listed with Craig Strong at Pacific Union International, is described as "the embodiment of natural luxury within an expansive mountainside setting."

Here's a look at the massive estate.
