The stadium's roof is the only one in North America that serves as an umbrella rather than a fully enclosed building, allowing it to remain open during games.
The outfield wall dimensions are asymmetric due to the specific footprint of the building site.
The park was originally named Safeco Field before T-Mobile acquired the naming rights in 2019.
The stadium contains a massive collection of local Seattle food vendors and craft breweries, focusing on regional Pacific Northwest cuisine.
It is constructed from 15,000 tons of structural steel.
The retractable roof weighs approximately 22 million pounds.
The stadium was built to replace the Kingdome, which was demolished shortly after the park opened in 1999.
T-Mobile Park is an outdoor baseball stadium with a retractable roof located in the SoDo district of Seattle. It serves as the home field for Major League Baseball's Seattle Mariners. The venue features a unique 'retractable roof' design that slides on rails to protect the grass and seating area from rain while keeping the sides open for natural airflow. Its playing surface consists of natural Kentucky Bluegrass and perennial ryegrass. The stadium structure incorporates significant amounts of steel and brick, reflecting the industrial heritage of the surrounding neighborhood. It offers a seating capacity of approximately 47,000 spectators for baseball events.
