Head north of downtown St. Louis and you may bump into a peculiar monument. A big rock, raised up on four levels of brickwork, sits near the intersection of Broadway and Mound Street in the Old North St. Louis neighborhood. Inconspicuous, this rock actually marks a significant site in St. Louis area history. This is where “The Big Mound” once stood, the largest of the Indian platform mounds that dotted the landscape where the city of St. Louis now stands. An extension of the famous Cahokia Mounds on the eastern side of the Mississippi River, these mounds were built by the Mississippian culture that thrived in this area between 900 A.D. and 1300 A.D.
I first heard about this landmark on a recent guided bike tour of the Mound City Interpretive Trail, sponsored by Trailnet. A local historian named Harold was our guide, and his knowledge of St. Louis is extraordinary. As we rode, we’d stop often and he’d throw out great history facts and stories about the Indian mounds and nearby communities. At one stop, he briefly mentioned a mound that once existed on the St. Louis side of the river. He said a monument even still stood for it. I knew right away it would be a great topic for this blog. When the tour was over, I headed over the river and found the rock. I can’t believe I hadn’t noticed it before. I often bike up and down Broadway on history hunting rides. It simply never caught my eye. But back in 1850, you couldn’t miss what stood there.
The mound stood approximately 30 feet high, extended about 150 feet, and had an oval shape. It had a flattened top that was about 15-18 feet wide. When St. Louis was initially settled by the French, it was called “La Grange de Terre”, which means “Earthen Barn”. It was later referred to simply as “The Big Mound” since it was the biggest of the twenty-seven Indian mounds that dotted the western side of the river. The image below shows an early survey map of the St. Louis mound group. Big Mound is circled in red.
In the 1840’s and 1850’s, St. Louis began to grow rapidly. It was decided to level “The Big Mound”, and it finally came down in 1869. The dirt and clay from the mound was used as back fill and to make brick for a growing city. Sadly, very little (if any) archaeological work was done during its demolition. However, some early St. Louis knew enough to take some daguerreotypes of the mound before it disappeared for good.
A granite boulder is all that remains today. It’s in an industrial part of St. Louis that doesn’t get much traffic. A plaque was once attached to the rock describing the significance of the site. It seems to have been stolen, but my guide Harold says it was intentionally removed to prevent it from being stolen. On the other side of the boulder, an attractive plaque of a Native American remains in place.
Get down to see the rock while you can. The boulder is schedule to be relocated to make room for a new 700 million dollar Mississippi River Bridge, scheduled to open in 2014. Look east from the rock today and you’ll see the giant spires of the new bridge directly in front of you. The new bridge will pass directly over the former location of Big Mound. While you are at it, head south of downtown and check out Sugarloaf Mound. It’s the only Indian mound in St. Louis that still stands.
(Update: Along with the completion of the bridge, the rock has been relocated a short distance to the east. It can now be found at the end of Mound Street, along with a few benches and descriptive signs.)
As discussed in the About This Blog page, my idea for this blog is twofold. I want to find historical places in St. Louis that pique my curiosity. While I do it, I want to find places in St. Louis where I can get a good cocktail. S
