If you have been up the KL Tower or its vicinity, you would have noticed the surrounding lush greenery around it. This is Malaysia's oldest gazetted forest reserve, the Bukit Nanas Forest Reserve, a 10-hectare ancient forest in the dense concrete jungle of Kuala Lumpur which is a rare feature in the world.
The city’s remnant of pre-historic tropical forest was gazetted as a forest reserve in 1906. Then in 1934, it was declared a Wildlife Reserve and Bird Sanctuary and finally in 1950, a Virgin Jungle Reserve.
By the way, the KL Tower which is the country's tallest is the world’s fourth tallest telecommunication tower.
