Neither of these two new Tates had a significant effect on the functioning of the original London Tate Gallery, whose size was increasingly proving a constraint as the collection grew. It was a logical step to separate the "British" and "Modern" aspects of the collection, and they are now housed in separate buildings in London. The original gallery is now called Tate Britain and is the national gallery for British art from 1500 to the present day, as well as some modern British art. Tate Modern, in Bankside Power Station on the south side of the Thames, opened in 2000 and now exhibits the national collection of modern art from 1900 to the present day, including some modern British art.
