The first permanent building in all of Mussoorie-Landour was also built in Landour in 1825. The house was built by Captain Frederick Young, the "discoverer" of Mussoorie, who was also the Commandant of the first Gurkha (or Gorkha) battalion raised by the British after prevailing in the Gurkha War. Young's house, "Mullingar" (hinting at his Irish blood), was the family home during the hot summers in the plains. Young's Dehradun-based battalion, then called the Sirmour (or Sirmoor) Rifles, was initially raised in a Gurkha POW camp in Paonta Sahib in Sirmour District – hence the name. The huge L-shaped building, with an outsized courtyard inside the bend of the "L", sits prominently atop Mullingar Hill in Landour Cantonment.
