Around The World In 80 Waves

Washington’s National Cathedral was only finished in the 1980s. At the tail end of construction a competition was held to design some gargoyles. One of the winning suggestions was to use Darth Vader’s head so they carved it out of limestone and installed it. Another space connection there is the piece of moon rock built into one of the stained glass windows.
