The Kuala Lumpur Tower (officially known as Menara Kuala Lumpur; referred later as KL Tower) is a tall tower located in Kuala Lumpur, Malaysia and was built in 1995. It is used for communication purposes and features an antenna that reaches 421 m (1,381 ft), which currently makes it the fifth tallest tower in the world. The roof of the pod is at 335 m (1,099 ft). The rest of the tower below has a stairwell and an elevator to reach the upper area, which also contains a revolving restaurant, providing diners a beautiful view of the city. Races are organised yearly where participants race up the stairs to the top. The tower also acts as the Islamic falak observatory to look for the crescent moon to mark the beginning of Muslim month of Ramadhan, Syawal, and Zulhijjah, to celebrate fasting month of Ramadhan, Hari Raya Aidilfitri and Aidiladha.
