On a visit to Auckland, New Zealand, Macau casino billionaire Stanley Ho Hung-sun was so impressed by the Sky Tower in Auckland that he commissioned a similar one to be built in Macau.
Construction started in 1998 and the tower was officially opened on December 19, 2001.
It is a member of the World Federation of Great Towers.
As well as being used for observation and amusement, the tower is used for telecommunications and broadcasting.
