Minute Maid Park, previously known as The Ballpark at Union Station, Enron Field, and Astros Field, is a ballpark in Downtown Houston, Texas, United States, that opened in 2000 to house the Houston Astros of Major League Baseball (MLB). The ballpark is Houston's first retractable-roofed stadium, and features a natural grass playing field. The ballpark was built as a replacement of the Astrodome, the first domed sports stadium ever built, which opened in 1965. It is named for beverage brand Minute Maid, a subsidiary of The Coca-Cola Company, which acquired naming rights in 2002 for $100 million over 30 years. As of 2016, Minute Maid Park has a seating capacity of 41,168, which includes 5,197 club seats and 63 luxury suites.
