Looking at the (probably?) trillions of pounds worth of Cold War infrastructure like bunkers, silos, airstrips, sub pens etc. that is not really used any more, I guess just left.
Though a collider tunnel that size may still be useful in 100 years. The SPS was built in 1976 and it's still useful nearly 50 years later. The tunnel can also be reused, just as the LHC used the tunnel for the LEP experiment.
