Limestone show caves with rivers in them, Etruscan tombs cut into cliffs, sunken roads dug so deep the sky is a slot overhead, wine cellars going down three storeys, Roman water tunnels still running, and catacombs.
All of it stays in the low teens all year, which makes this the best page on the site for a heatwave — and none of it cares whether it is raining.
Out after breakfast, back with the evening still yours.
