The stadium was located in the
North Central portion of Regina. The first facility on the site, a rugby (Canadian football) field known as Park Hughes, was built in 1910. In the same year that Park Hughes was built, the Regina Rugby Club was founded. For much of its first decade, the club played at venues such as Dominion Park (1910-1916) and the municipal exhibition grounds (1919-1921), the team played its first game at Park Hughes on October 15, 1921. The field had recently been enclosed with an eight-foot fence and configured to accommodate
soccer as well as Canadian football. Nonetheless, it remained rudimentary even by the standards of the time. The playing surface was little more than plain dirt. When heavy rain turned the field to mud, the team was compelled to relocate games to other venues in the city, including the RCMP barracks. At the time, the barracks housed a unit informally called the
Roughriders who were tasked with breaking in wild broncos for the force. In 1924, the Regina Rugby Club would adopt the
Roughriders nickname as their own. In 1928, the fence between Park Hughes and Park de Young, a neighbouring baseball field built in 1918, was removed, and the site was reconfigured into a larger venue under the Park de Young name to accommodate the growing number of fans. A football gridiron was laid out at the site. However, for a time between 1929 and 1936, the Roughriders moved their games back to the exhibition grounds, which could accommodate more spectators. His artificial glass eye was once jolted out of its socket when he was tackled. All play stopped while players from both teams hunted for the missing eye. When found, Taylor cleaned it, then popped it back into its socket and resumed play. When the stadium was first built,
minor league baseball was a relatively popular spectator sport in much of North America, including Western Canada. However, as
Major League Baseball gained more exposure on the then-new medium of
television, baseball attendances dropped to the point where venues like Taylor Field ceased to be economically viable ballparks. In 1966, a second permanent grandstand was constructed, significantly expanding capacity for Roughriders games while also effectively converting Taylor Field to a football-only stadium. Former Rider receiver Hugh Campbell said in the documentary
CFL Traditions in 2003. "When I first saw the stadium in Regina (in 1963), it looked like a farmer had built it, you know, like they'd just added on a few pieces here and there and half of the dressing room was dirt floor, where us rookies got to be. But we had a hook for everybody to hang their clothes on so that was a pretty good deal." Renovations during 1978 and 1979 increased the seating capacity by about 7,000 seats with the addition of an upper-level grandstand on the west side of the stadium, in addition, the stadium gained an artificial turf surface (3M Tartan Turf) which replaced the natural grass surface previously used. This was, in turn, replaced with an OmniTurf system (a rudimentary forerunner of today's infilled artificial turfs that used sand as a support material) in 1988, which would be replaced by AstroTurf in 2000. In 2005, a new scoreboard was installed, which included the stadium's first permanent giant replay screen. In 2005, Mosaic Stadium gained refurbished washrooms, concessions and refurbished seats on the east side, a new sound system, and the new
SaskTel MaxTron video board. In 2006, a VIP deck and stands were put in place in the south endzone, allowing the football club to host its corporate game day sponsors. On July 31, 2008, the Roughriders announced that temporary seats would be added to the stadium due to high demand for ticketsthe team had sold out every home game for the 2008 season. With tickets in high demand coming off their Grey Cup season, an extra 2,145 seats were added, bringing the capacity to 30,945. The seating was first put to use during the Labour Day Classic against the Winnipeg Blue Bombers. Following the
2008 West Semi-Final game on November 8, 2008 against the
BC Lions, the temporary seats were taken down, putting the capacity back to the original number of 28,800. 2,145 temporary extra seats were put in place for
2009 season. Temporary seating was again put in place for the
2010 season; however, the additional seating only raised capacity to 30,048. On February 24, 2012, the Roughriders announced a $14 million renovation plan known as the "Legacy Project" to prepare the stadium for hosting the
101st Grey Cup. Riders chairman Roger Brandvold was quoted as saying "Replacing Mosaic Stadium still remains our top priority, but certain upgrades needed to be made to get us through the next few years and especially the 2013 Grey Cup". The first stage of the renovations were finished in time for the start of the 2012 season, with the addition of 7,000 extra seats and 27 new corporate suites (arranged to give the stadium a more "bowl"-like feel), additional bathrooms and concessions, the
SaskTel MaxTron video screen and scoreboard upgraded to a 60-foot
LED screen (with a second display directly alongside, shaped like the province of Saskatchewan), a new 55-foot video screen attached to the west grandstand, and ribbon screens along the bottom of the grandstands. For the 2013 season, its capacity was expanded to 45,000 with temporary seating, which were removed for the following season. ==Notable events==
