Bayterek is the capital's symbol and business card. Bayterek tower sits in the very middle of the capital's new administrative center . Everything in this monument is symbolic: the golden sun on the top of the tree, its height of 97 meters, the internal architecture divided into three zones which represent the three fundamental universal principles. This "poplar" (in Kazakh – bayterek), made of metal, glass and concrete, is architecturally unique and grandiose in appearance. It is a metal structure of 105 meters tall, 1000 tons heavy, built on five hundred poles. It is the first time that a 22 meter diameter and 300 ton sphere of "chameleon" glass, which changes color with the sunlight, is suspended at such a record-breaking height. Dominating the new capital, it is an architectural symbol of renewal, the symbol of Astana, the symbol of Kazakhstan.
