Strollling Around Passau

The Roman Museum is where I headed first today.
Apparently, there was a Roman fort here in Passau and later, during the Middle Ages, there was a castle built on top of the fort.
The museum was in the fort/castle and here is how it was built to keep it strong and fortified, but also to prevent it from being flooded:

On display were lots of Roman keys, locks, and even piles of metal junk:

There were several Roman swords and even a helmet:

The museum even dug up some Roman jewelry:

After the museum, I headed up to the confluence of the three rivers before checking out the rest of the city.

I'm not sure if you can tell from this picture, but you can actually see the different colors of the rivers in the confluence:

Here is the Inn River:

 Here is the Ilz River:

And, here are two of the Danube River (there were lots of cruise ferries):
