Bukit Nanas is a landmark of Kuala Lumpur, Malaysia. It contains the only virgin tropical rain forest left in the city. The city planners are dedicated to preserving this jungle located in the heart of Kuala Lumpur. Originally home of the Malayan Tiger and elephants, this jungle is still home to monkeys, pythons, squirrels, and monitor lizards.

Bukit Nanas is situated in the Bukit Nanas Forest Reserve, which is open to the public. There are jungle trails, a visitors centre, and a forestry museum. There used to be a cable car service that has been discontinued since the 1980s.

In the 1990s, the Kuala Lumpur Tower, which is the fifth tallest telecommunications tower in the world was built on the hill. It has an observation deck, a banquet floor and a revolving restaurant.

Two of Malaysia's many British colonial era schools, which exceeded hundred years old, are also situated on this hill. They are St John's Institution and Convent Bukit Nanas. St. John's Institution has been gazetted as a National Heritage Site by the federal government.

St. John's Institution (Malay: Sekolah Menengah Kebangsaan St. John) is a secondary school for boys (sixth form is co-ed) and one of the oldest schools in Kuala Lumpur, Malaysia. The school is widely known as SJI and the students of St John's Institution bear the name Johannians.

The school is named after Jean-Baptiste de la Salle, the founder of the De La Salle Christian Brothers Order and also known as the Patron Saint of Teachers.

SJI consists of a primary school and a secondary school. The primary and secondary schools initially were fee paying missionary schools. They functioned together until the increase in enrolment of pupils led to a separation of the primary school in 1960. The primary schools are formally known in Malay today as Sekolah Kebangsaan St. John (1) and Sekolah Kebangsaan St. John (2) while the secondary school is called Sekolah Menengah Kebangsaan St. John.

SJI is among the first 30 schools selected into the Cluster School scheme when it was first introduced in 2007 by the Ministry of Education, Malaysia .
