Cromwell Island in Flathead Lake is up for sale at $72 million. The 348-acre property is the largest private island with a single owner west of the Mississippi River, according to the property listing.
The island includes three miles of shoreline, 45,000 square feet of living space and a dock with five boat slips, one with space for a 70-foot boat.
Robert M. Lee — an automobile and antique arms collector, explorer, author and conservationist — purchased the property in the 1980s with his wife, Anne. The Lees partially completed construction on the island before relocating to Lake Tahoe. Lee passed away in 2016.
The main home on the property, while unfinished, “has a magnitude of presence reminiscent of Versailles,” the listing states. The sprawling residence is made of concrete and limestone from Gardiner.
