So here is my proposal for a fictional place I call Mozart city. As could probably be deduced from the name, Mozart and his family run the place.
Just to clarify this is in an alternate universe where the great composers are immortal
Mozart and his family
Leopold Mozart runs a bank. Franz Xavier Wolfgang Mozart is the substitute mayor. Wolfgang Amadeus Mozart has a lot of things he does. Here is a list of things he does:
Horse riding teacher
Gives money to those wanting to start an account
Cheers up someone if he/she is really upset
Give directions to the other composers' places
That is a lot. I think that in order for Mozart to achieve all this every day, his home has to be in the same building as the mayor's office.
Size and layout
The city is 50 miles in radius. That is the average daily distance of Mozart's horse. Starting from the outside, it is mostly residential. Then in the middle, there are stores and restaurants. Grocery stores, knitting supply and pattern stores, music stores, bookstores, and restaurants make up the majority of this commercial sector. Then as you get closer to the center you have concert halls, homes of musicians, banks, a few factories(mostly for producing money that is circulated), a composer meeting hall, and then finally, smack dab in the center the mayor's office/Mozart's home.
I will draw a map of this city if you want me to. But it will take a while. But is a city like this plausible(circular shape I think would make it harder to design to be functional)?
