Washington National Cathedral
Washington National Cathedral is the 6th largest cathedral in the world
Believe it or not, there is a Darth Vader gargoyle on the top of the West tower!
One of its windows, the Space Window, contains a piece of real lunar rock!
The entire cathedral weighs about 150,000 tons!
The Cathedral is not government funded, which means the public donates money so the cathedral can be taken care of.
