The UK has a window tax.
A long, long time ago, homes had a property tax based on the number of windows. Basically, the bigger house, the more windows, the more tax paid. In an effort to reduce tax, homeowners bricked-up windows like this house at the end of our road.
If you live or visit the UK, take a look around and marvel at all of the windows that have been bricked-over! They are everywhere!
