Could I interest you an a Midwestern castle? One thing you should know is that it's mostly underground. Oh, and it's also a doomsday bunker.

This is what's known as Subterra Castle. It was a missile base for Atlas-E rockets which had nuclear warheads. The official website gives you some background on what this site was originally used for:

This site was built by the Army Corps of Engineers in the late 1950’s and was operated by the U.S. Air Force from 1961 until 1965, when it was decommissioned and abandoned by the military in favor of newer rocket technology and stronger underground launch facilities. The structure is “semi-hardened,” which according to the Department of Defense means, “construction that provides protection against near-miss detonations of large general-purpose military bombs and direct hits from smaller munitions.”

The couple that bought the property after the government decommissioned it are getting older and have decided to sell it. Their official website shows that there is over 11,000 square feet of space. Wonder if that includes the 150 feet of underground tunnels?

How many homes do you know that have a 47-ton drive-in garage door capable of withstanding a nuclear strike? This one does.

If the zombie apocalypse becomes a reality, you're in good shape here. There are a couple of observation towers plus an 8 foot security fence around the underground castle complex.

There's also a solar greenhouse with hot tub so you can live the lifestyles of the rich and famous while the rest of civilization deals with a nuclear meltdown.

Subterra Castle is an easy half-day drive from the tri-state area. The website gives general directions:

The 33-acre estate is situated in the Kansas Flint Hills about 25 miles west of Topeka, Kansas, only about 10 miles off Interstate 70, and within 2 hours of Kansas City International Airport.

If you're interested, you better bring some big bags of money. The website listing this underground castle shows it's north of $3 million. Small price to pay for living like Will Smith in "I Am Legend".
