Welsh-Ryan Arena was built in 1952. In 2014, the basketball court at Welsh-Ryan was redone and a new Jumbotron was installed. While exact figures on what the new seating capacity will be after the renovations are complete, it's likely that Welsh-Ryan and Rutgers' Louis Brown Athletic Center will remain the Big Ten's only basketball arenas with under 10,000 seats.
