While visiting Vienna, there are ruins on display in Michaelerplatz (central Old City), so cool.
I've always been confused how this works. Did people shovel soil on top of buildings then build new buildings on that? Why? Did it accumulate naturally perhaps during periods when a site was unoccupied? Would some buildings be higher than their older neighbors, with entrances above street-level until everyone else caught up?
