The Millennium Dome was a large dome-shaped structure built in London, England, to celebrate the start of the 3rd millennium. It was open to the public from January 2000 until December 2000 and attracted over 6 million visitors.
The dome was designed by architect Richard Rogers and cost over £750 million to build. It was the largest dome in the world at the time of its construction. The dome was made of a lightweight PVC fabric and was supported by a steel framework.
The Millennium Dome was intended to be a symbol of Britain's progress and innovation. It featured a variety of exhibits and attractions, including a time capsule, a giant interactive map of the world, and a 360-degree cinema. However, the dome was not a commercial success and was criticized for being expensive and lacking in substance.
After the Millennium Dome closed, it was used for a variety of purposes, including as a music venue and a conference centre. In 2012, the dome was converted into a sports and entertainment complex called The O2. The O2 is now home to a variety of attractions, including a music arena, a cinema, and a bowling alley.
The Millennium Dome was a controversial project, but it remains an iconic symbol of the start of the 3rd millennium.
