Retractable Roof
You've decided to build a dome with a roof that opens and closes, also called a retractable dome. Great choice! Retractable domes are great for ballparks because they can be opened on nice days and closed on rainy or hot days. This way, no games ever need to be cancelled! The SkyDome in Toronto, Canada, was the first retractable dome to be built over a ballpark. Today, most domed stadiums are built with retractable roofs.
