Chautauqua Los Seis De Boulder Memorial

The City of Boulder, in partnership with the United Mexican American Students y Movimiento Estudiantil Chicanx de Aztlan (UMAS y MEXA) and the Colorado Chautauqua Association (CCA) dedicated an interpretive memorial for the “Los Seis de Boulder.

” On May 27, 1974, a car bombing killed three Chicano activists near the Chautauqua Auditorium. Two days later, three more Chicano activists were killed in another explosion in Boulder. This event is remembered as the Los Seis de Boulder (the Boulder six).  

The language for the memorial was provided through a collaborative effort with relatives of the deceased, CCA, UMAS y MEXA and Mary Young, a Boulder City Council member. The Chautauqua Building and Grounds Committee approved the stone and inscription. The memorial is a lichen covered Lyons sandstone with engraved text. The memorial is located at Chautauqua Park on the north lawn on the east side of the Auditorium. 

The memorial was approved by the City of Boulder’s Historic Preservation program on January 10, 2020 and installed on May 27, 2020. The city’s Historic Preservation program helps preserve the community's unique heritage, culture and character by protecting buildings and sites that are reminiscent of Boulder's past. Community interest in preservation has resulted in more than 1,300 designated historic properties in Boulder, including more than 200 individual landmarks and 10 historic districts.
