The Olympic Gymnastics Arena, also known as the KSPO Dome since 2018, is an indoor arena located within the Olympic Park in Seoul, South Korea. It has a capacity of 15,000. It was constructed between 31 August 1984 and 30 April 1986, to host the gymnastics competitions at the 1988 Summer Olympics. The roof was designed by David H. Geiger. It is a self-supporting cable dome – the first of its kind ever built – with a four-layer fabric cladding.
