Believe it or not, that massive blue bear outside the Denver Convention Center wasn’t just installed to be a great background for selfies. Like each piece of public art, the Big Blue Bear (official name “I See What You Mean”) has an origin. Discover the bear’s story, as well as the history of many other pieces at one of Denver Arts & Venues’ free guided Public Art Tours this summer.

This year marks the 10th anniversary of the series, and to celebrate, Denver Arts & Venues is adding a few new tours to its roster, including the return of a guide through Denver International Airport’s controversial collection—one of the largest bodies of work at a U.S. airport—a guide to the history and art of Union Station, and a tour of the contemporary pieces dotting the Denver Art Museum campus. These additions round out a schedule of 13 leisurely, location-specific tours that will be offered throughout the summer, including the return of two bicycle tours (of the Cherry Creek Trail and Downtown Denver).

In total, the backstories of more than 80 pieces of art will be shared throughout the season. Groups are capped at 15 people, so be sure to RVSP in advance. And bring your questions—Denver Arts & Venues staffers and the expert volunteers who lead the walks encourage dialogue. Who knows, you might just become the city’s newest public art trivia master.
