On this day, 28 years ago, May 13, 1997 (April 7, 1997 in the lunar calendar), the height of the "Millennium Building" in Britain caused controversy. On May 13, 1997, the design height of the British "Millennium Building" to be built to welcome the arrival of a new millennium caused controversy in the UK. The construction of the Millennium Building was announced in 1996. It will stand in the famous Financial City of London and become one of the symbols of London. According to its design, it has a height of 386 meters, a total of 92 floors, and a usable area of 140,000 square meters. It can accommodate 10,000 people for office use. It is expected to cost 400 million pounds (about 640 million US dollars). It will become the tallest building in the UK. Proponents of the "Millennium Building" design height believe that this height can represent the City of London's status as one of the world's financial centers and become a new landscape for London. Opponents believe that it may have a greater impact on the surrounding landscape, making many originally magnificent buildings such as St. Paul's Cathedral appear very small and making the city's landscape out of balance. Currently the tallest building in the UK is the Skylark Wharf Building in the City of London, which is 244 meters high.
