Another view, another window...

This is the view from another window in my apartment, on the other side of the building. We often have lovely sunsets although I´d rather see the horizon without obstacles in the way. Out of curiosity I checked the view I posted recently from another window on my faithful Silva walking compass and it reads West, and this window with the sunset reads Northwest...I´ve always understood the sun rises in the East and sets in the West! Summat´s wrong!
