Colorado took part in the “National Memorial to Lives Lost to COVID-19” Tuesday, lighting the Denver City and County building to honor and remember those who have died from COVID-19.

The building was lit in amber lights and ringing bells and those who have lost family members were asked to light candles.

Cities around the country participated in the ceremony, including Washington D.C. which featured a lighting at the Lincoln Memorial Reflecting Pool and several live-streamed speakers.

“We gather tonight as a nation in mourning to pay tribute to the lives we have lost,” Vice President-elect Kamala Harris said in the ceremony.

“For many months, we have grieved by ourselves. Tonight, we grieve and begin healing together.”

The ceremony also featured a performance of “Amazing Grace” by COVID-19 nurse Lori Marie Key from the St. Mary Mercy Livonia Hospital in Michigan.

“To heal we must remember,” said President-elect Joe Biden. “That’s why we’re here today.”

Over 400,000 people in the U.S. have died from COVID-19 so far, including more than 4,500 Coloradans, according to the Colorado Department of Public Health and Environment.

There have been over 377,000 COVID-19 cases in Colorado.
