Hello Hans,

- The roads of the Roman empire
- The gothic cathedrals
- The Semmering railway
etc.

You are perfectly right, my selection of engineering achievements rather lists milestones than monuments for eternity. Very few milestones which are monuments at the same time survived the ages. The Roman roads are a good example as are their concrete buildings like the Pantheon in Rome. 2000 years before concrete was reinvented in modern times (only that the descendants (all of us in Europe that is) of the Romans seem to have difficulties making concrete road and motorway bridges which last longer than 50 years...).
