The Millennium dome opened on 1st January 2000. It has a riverside walk with 'ecological terraces' on the river edge and a 'Central Park' which, in due course, will become a feature in a housing estate. The Central Park was designed by Michel Desvignes and the detailing has a Parisian character, with granite curbs, an abstract fountain and lines of trees. A sculpture by Anthony Gormley stands on a platform in the river. The Millennium Dome reopened as The O2 in 2007 and became the world's busiest music venue. In 2017 a building by Santiago Calatrava was announced.
