Join Euclid Public Library for Diamond Fest, a full day of fun for people of all ages as we celebrate 90 years of service, learning, and community. Held at Sims Park on Saturday, August 9, 2025, this free event will feature something for everyone, including live entertainment, local vendors, and delicious bites from a variety of food trucks.

Families can enjoy Sparkle Park from 11:00 a.m. to 4:00 p.m., featuring DJ music, balloon twisting, a foam party, bounce houses, photo booths, and a spectacular bubble show by Guinness World Record Holder Dr. U.R. Awesome. Adults and seniors can relax at the Diamond Den inside Henn Mansion with retro games, crafts, caricature artists, and an author talk with Cleveland writer Susan Petrone.

Visitors can also browse unique handmade goods at A Gem of a Marketplace and explore local history through an exhibit by the Euclid Historical Society. In the evening, the celebration continues at the Carat Club Tent from 5:00 to 7:00 p.m. with an electrifying concert by The Bottom Line Band, along with beer and more for adults to enjoy.
