Located on the corner of the Thames, O2Arena is one of the largest stadiums in London and even the UK. With its unconventional design, it looks like a UFO ready to take off from a distance. It is also one of the busiest performance venues in the world. After him, such as Manchester Arena and New York Madison Gardens are all familiar venues. It can be seen that it is popular with major sports events and star concerts. For example, Eason Chan, Leehom Wang, and Huimei Zhang have all sang here. In addition to watching games and performances here, O2Arena also provides roof climbing services. Under the guidance of a guide, it is also a good experience to climb the dome of O2Arena and overlook the scenery along the Thames River.
