They don't destroy it, only cover it up again, pave over and put up a parkinglot. Have you ever been to Italy?
They are chokin in ruins of which the people care little as there are so many. They however don't have the best economy of Europe, especially the small towns.
Besides, why would you want them to dig up ruins just so that the ruins can wither away even more in the wind and acid rain? It survived this long, it can stay put a century. Then the parking lot is too old and perhaps we can dig it up.
Not quite.
