Helping to revitalize the eastern part of downtown Houston, this engaging ballfield premiered in 2000 and has proven to be a fan favorite. The home of Astros baseball was constructed on parking lots near the old train station and even incorporates part of Union Station in its design. The intimate venue boasts a spectacular, retractable roof that opens when the weather's mild and closes when rain appears or when air-conditioning is needed. The natural grass field has old-school appeal, as do manual scoreboxes and upclose seating. One-hour tours are available, and restaurants and bars are located in the vicinity.
