Its funny you picked the first link as one of your favorites Airith, the picture of the cathedral is from one of my favorite children's books: Lebek: A City of Northern Europe Through the Ages (http://www.amazon.com/Lebek-City-Nor...0132554&sr=8-1) The book is a clone of the types of books by David MaCaulay (Pyramid, Cathedral, City, Underground, etc.). It consists of a series of drawings (with some descriptions) showing the development of a fictional northern European city on the Baltic (based on Lubeck) from 1000 AD to 2000 AD. The drawings are good looking and the book is great background material for understanding how urbanization functions in the growth of cities.
