Someone very thoughtfully (thank you, DD!) sent me a link to this article:

BLAINE — In real estate, the term “unique” is a common description, even for a stick-frame rambler. But this property is as unique as they come.

For sale at $1.5 million: a five-story massive concrete building, on top of which once sat a 70-ton rotating radar.

This was during the Cold War, and the radar was part of a system on the lookout for incoming Soviet bombers. It was in a prime location to search the horizon, right by the Canadian border, with a magnificent view looking out at the San Juans.

Potential buyers ought to have no earthquake worries. Each floor has four solid concrete columns. Each column is 3 feet square. Outside walls are a foot thick and reinforced with rebar.

“It was explained to me that it was constructed to withstand a nuclear attack,” says Stefanie Fuller, who in 2003 was in charge of selling the surplus radar tower for the state.

But here”s the real money shot – ad with pictures!

Kinda looks like one of those old German flak towers that they can’t cheaply tear down these days.

I remember looking at one of those microwave relay stations that were for sale years ago…it was constructed in a similar ‘-nuke-resistant’ fashion. They’d make awesome retreats if you could modify them for full-time habitation without compromising their integrity.
