But why would there be two banks so close to each other? And why (although I can accept the early screenshots were more for show) would this building always be so close to a church? From T1, the clinic was always built near the church as it was one of the first buildings. Although again that doesn't prove anything.

While that seems a resonable assumption that the blue and white building is the hospital, do you know for sure? It also looks like quite a small building for a hospital. If that is the hospital then it seem very unlikely that my idea on the other building being a clinic is right, as the clinic would not be much different in size to the hospital.

I have not seen anything that resembles a bank, so it most likely is one. Although could the bank be that enclosed building?
