Set to open on 17 June, the Tate Modern Switch House – named after the part of the power station that the new galleries occupy – expands the museum by 60% to accommodate the surging numbers of visitors, which reached 5.7 million last year, well over double the number the building was designed to cope with when it opened in 2000. But the arresting brick ziggurat is also a physical symbol of the effect the Tate has had on its surroundings. — theguardian.com
