The Detroit Lions football team is based in Detroit, Michigan. They play their home games at Ford Field, which is a domed American football stadium located in Downtown Detroit. Ford Field has a regular seating capacity of approximately 65,000, expandable up to 70,000 for football games. The stadium has been the home of the Lions since it opened in 2002. The team was originally founded as the Portsmouth Spartans but relocated to Detroit in 1934, where they were renamed the Lions. The Ford family has controlled ownership of the Lions franchise since 1963, and the Ford Motor Company holds the naming rights to Ford Field.
