Answer :
The Millennium Dome opened on 31st of December in the year 1999 and closed on 21st December in the year 2000. The main reason behind the closing of the Dome was that the visitor receipts were unable to cover the expenses. I hope that this is the answer that has actually come to your desired help.
The Millennium dome in Greenwich, London, is a huge white tent-like structure. The idea to build the Millennium dome was first put forward in 1994 by the then Prime Minister John Major, and was built to mark the end of the 20th century and the beginning of the 21st century. It contained about fifteen themed ‘zones’ in it.
It was later heavily criticized for being a waste of resources and money and that only half of the expected projected attendance rate of 12 million visitors turned up during the year of its opening.
It was opened on 31st of December in the year 1999 and closed on 21st December in the year 2000. The dome was later sold in December 2001 and later reopened as the O2 in 2007.
