June 30th is a special day in St. Louis. It’s #Arch630Day! A day dedicated to celebrating our iconic Gateway Arch and its impressive dimensions: 630 feet tall and 630 feet wide. It’s more than just a monument; it’s a symbol of our city’s spirit, and we want everyone to join in the fun! 

For the past few years, St. Louis has embraced the Arch 630 Day Stacking Challenge, and it’s always a blast! Businesses and organizations across the region get creative, measuring something unique to their operations and calculating how many of those items it would take to reach the Arch’s towering 630 feet. Imagine: How many stacked baseballs? How many scoops of ice cream? How many… well, you get the idea! Last year, we saw that it would take a staggering 158 elephants at the St. Louis Zoo to equal 630 feet. What will you come up with this year? 

We’re calling on all St. Louis businesses, organizations, and individuals to take on the Stacking Challenge again! It’s a fantastic way to showcase your unique identity while celebrating a shared St. Louis icon. Share your calculations and a photo of your item using #Arch630Day on social media! Feel free to create your own graphic or use the provided graphics in this Google Folder.

Want to take the celebration to new heights (pun intended!)? Here are just a few ideas to get your creative juices flowing for #Arch630Day: 

Get Creative & Come Visit! 

And don’t forget the best way to truly appreciate the Arch’s magnificent 630-foot stature: come visit! Walk the grounds, take in the breathtaking views, and capture your own photos of this architectural marvel. Whether you’re admiring its towering height or its impressive span, seeing it in person really brings home the “630” of #Arch630Day! 

Why celebrate #Arch630Day? Because the Gateway Arch isn’t just a structure; it’s a testament to human ingenuity, a symbol of westward expansion, and a source of immense pride for our community. It connects us to our history and inspires us for the future. 

Let’s make this the biggest and best #Arch630Day yet! Start planning your participation now. Whether you’re stacking, selling, broadcasting, or just sharing your Arch love, we want to see it!
