Tokyo Sky Tree in Japan has become the world’s tallest free-standing television tower after crossing a height of 601m during construction.
The $790m tower, which will top out at 634m, was designed by Tadao Ando and features an anti-seismic design that includes underground pilings spread out like the branches of a tree.
The tower comprises an outer steel frame and an inner shaft of reinforced concrete that can move separately and cancel out their seismic energies.
The tower will include two observation decks, 300 shops and restaurants, an aquarium, planetarium and a dome theatre upon completion.
Construction is expected to be complete by the end of 2012.
