Richthofen Castle

Source: Google Maps, at 7020 E 12th Avenue, Denver, CO

This is the entrance to the Richthofen Castle.  You can search for pictures of the castle, but this is what you see from the street level, which is what us peasants see.  This is technically in Denver, but before it was annexed (in 1903), it was in the town of Montclair.  It was built in 1887, before the silver bust of 1893.

I am thinking of doing a series on spooky places in the "Aurora area", and this definitely would be in the top ten.
