It's the ultimate collectible for the military fan, a full-fledged Civil War fort within commuting distance of Montreal.

The bidding on eBay Saturday afternoonwas up to$2 million US, and rising fast. The reserve bid,the minimum the property will go for,is somewhere in the neighbourhood of $10 million US.

The property is Fort Montgomery, a limestone fort that sits on an island in Lake Champlain, cheek-to-cheek with the Canadian border.

Built in 1844, the fort was occupied during the U.S. Civil War, but never saw any action. It is now listed by the United States government under the National Register of Historic Places.

It was recently put up for sale on the eBay internet auction site by the current owner, Victor Podd of Boca Raton, Fla.

Podd's father bought the fort in 1983 to house the headquarters of his company, Powertex. But the Podd family thought better of the idea a few years ago and offered to donate it to the State of New York for use as a park. The offer was declined, and Podd offered it on eBay instead.

The property includes a substantial limestone fort that sits on an island near Rouses Point, N.Y., more than three kilometres of waterfront and 113 hectares of land that abuts the Canadian border.

"A true developers dream," the listing says, adding that it would be suitable for a nursing home, offices, hotel, warehouse or a grand house.

Bidding ends June 5.
