This pair of artists have drawn reconstructions of the ancient world. Here are a couple of from their Ostia Antica project. The first is Ostia:
I have been to Ostia several times, and I never realised that the river ran to the right, as you walked down the main street, starting from the railway at the right.
At the top of the first image is the new port built by Claudius, Portus. And here it is!
The illustrations have been made for books. They clearly need to be commissioned to do many more of these!
