Raising the Flags on Colorado's Sesquicentennial

Three new flagpoles are going up at the Museum of Boulder, a gift from the Rotary Club of Boulder. On August 1st, Colorado Day, we'll raise the United States flag, the Colorado state flag, and the (unofficial) City of Boulder flag for the first time. The timing isn't an accident: 2026 marks Colorado's 150th anniversary of statehood, and we wanted a way to mark it that people could see from the street.

Join us for light refreshments on the morning of Saturday, August 1st at 10 AM, with flags up by about 10:20 AM. It's free, it's quick, and it's a good excuse to be outside to celebrate Colorado's 150th Anniversary.

Also, in honor of Colorado Day and the state’s 150th anniversary, admission to the Museum of Boulder will be FREE for all visitors on Saturday, August 1. Explore Boulder’s history, culture, and community through engaging exhibitions, interactive experiences, and stories that connect our local history to Colorado’s remarkable past.
