Titan Missile Silo Museum
1580 W. Duval Mine Road
From the early '60s through 1982, 18 Titan Missile silos surrounded the city of Tucson, armed with 330,000-pound, 110-foot-long nuclear ICBMs designed to annihilate those who would dare to steal our precious bodily fluids. One silo southwest of town is now a museum where visitors can go underground and explore the spare four-man crew quarters and the shaft itself, where a decommissioned missile is on display. Tours cost $7.50, with a $1 discount for seniors. Children 6 to 12 pay $4 and kids under 6 get in free.
