T-Mobile Park
T-Mobile Park in Seattle, then called Safeco Field, from the top of the upper deck during a Mariners game in April 2007, with the retractable roof rolled back and downtown towers beyond left field.
The roof is the clever part: when it closes it covers the whole park without sealing it in, so rainy-day games still feel open-air. On a dry night it parks to the side and the sky comes back. The park opened to a capacity crowd on July 15, 1999, took its current name after the 2018 season, and a picnic patio on the outside corner looks out over Puget Sound.
