You can walk across to various parts of the school. LORD BUDDHA STATUE: Close to Deolo there is a small rock garden in which you will find this nice statue of Lord Buddha sitting in a lotus position.

MACFARLANE MEMORIAL CHURCH: Macfarlane Memorial Church was established in 1891 in memory of Rev. William Macfarlane, the first missionary who came to Kalimpong. One of Kalimpong's most imposing churches, this church was severely damaged by a 2011 earthquake, when one of its steeples came crashing to the ground. After renovations, the church is now open to visitors and believers alike, and its wood-buttressed Gothic interiors are a wonderful place to spend a few moments in quiet contemplation.
