Built in 1832, Sir George Everest's House and Laboratory, also known as Park Estate, is a popular heritage site. This popular house was from where Sir George Everest helped the British measure the height of the world’s greatest peak, Mt Everest. For his contribution, the peak that was earlier called Peak XV, was named after him. The location of the house is strategic and at the time of Sir Everest, it was used as an observatory to view mountains that demarcated the boundaries of British India. Today, the house is being maintained by the government of Uttarakhand and is open to tourists all year round. From here, one can get a spectacular view of the Doon Valley and the Himalayas. It is located at a distance of about 8 km from Mussoorie.
