Some more details:
The central island would have been the major river crosing at first. Much easier to cross from shore to island to shore than cross the river all at once. That would also have made the island the prime location to place the tollgate, which eventually grew into the castle.
With the new bridges downstream (and one of them should be called "Newbridge", no matter how old it is ) the island obviously no longer serves as toolgate. But if we ever get around to mapping the castle and the island in more detail, there should still be an imposing gate structure on the island
Just thought of something else: we may also want to have a toll gate on the river, for ships passing from the lake (and further upstream?) to the ocean. Again, the central island could (still) fulfill that function.
Once we have the large-scale map more or less worked out, we should proably make a higher resolution one for the city itself.
