Sure, you’ve admired the Arch from afar. You might’ve even done the tour at some point. But here are six things you can do (for free!) this month at the Gateway Arch that you might not have known about.
1. Yoga: You could stretch out on the Arch grounds just about any time without raising too many eyebrows, but from 9 to 10 a.m. on Saturdays in May (weather permitting) you can join others and instructors from the South City YMCA.
2. Gaze at the stars: Take in the stars (telescopes provided) with the St. Louis Astronomical Society from 8 to 10 p.m. May 9.
3. Find ghosts: In the mood for something a little eerie? Take a walking tour of the Arch grounds May 9 and learn about the people and events of its past.
4. Re-enact history: The British are coming on May 24! Learn about the 1780 Revolutionary War battle that happened on the Arch grounds, including historic attire, live musket demonstrations and cannon firings.
5. Hunt for treasure: Park Quest lets kids ages 3 to 12 use maps and compasses to discover hidden clues from 10 to 11:30 a.m. May 29.
6. Walk: OK, you can walk the Arch grounds whenever you want, but this guided tour will teach you more about the Arch, including how it was built and facts about the grounds, colonial St. Louis and the Mississippi River.
And if all else fails, as the Milwaukee Brewers recently pointed out, you can always invite Wang Chung to the Arch for a dance-off.
After that dance performance by Jim Henderson, Tyler Thornburg, Zach Duke, Will Smith, Brandon Kintzler, Wei-Chung Wang and Marcus Hanel, the Brewers lost to the Cardinals. Plan your dance activities wisely.
