The Big Four Roadhouse is Calgary's newest live entertainment venue. It fills the 60,000 sq. ft. upper level of the newly renovated Big Four Building at Stampede Park, with a built-in stage, bars, and in-house sound and lighting. Altogether the building has 118,000 sq. ft. of exhibit and event space across two levels, and it hosts concerts, trade shows, corporate functions and celebrations. During the Calgary Stampede, the Roadhouse has live country and rock music every night, and concerts are free with park admission. It is open to all ages during the day and becomes an 18+ licensed space after 6 p.m. The building is named for the "Big Four" cattlemen who funded the first Stampede in 1912.
