I'll have to look that place up too. Thanks!

That's an amazing place too. I was just looking at images from it. These fortifications are like many religious buildings though, and I have to wonder if the people laboring to make them were forced or not or heavily taxed to pay for them. Supposedly a lot of European fortifications were built by paid builders. Even then though, the rulers had to get that money through taxes. The price of security perhaps?
