View of St. Louis from the Monks Mound at Cahokia Mounds State Historic Site.
Monk's Mound covers almost 14 acres and rises 100 feet. A part of the larger ancient city of Cahokia that at its peak housed 10-15 thousand people.
Took this photo a couple of years ago while at a Blues Festival in St Louis. I'd like to back at some point. The bridge was built back in 1868 making it one of the oldest bridges in Missouri, it carries both trains and vehicles from downtown St. Louis MO, to East St Louis IL. #Trovember
