Baltit Fort or Balti Fort is an ancient fort in the Hunza valley in the Northern Areas of Pakistan.
In former times survival of the feudal regimes of Hunza was ensured by the impressive Baltit fort, that sit on top of Karimabad. The foundations of the fort are said to date back around 700 years, but there have been rebuilds and alterations over the centuries. In the 16th century the Thum married a princess from Baltistan who brought master Balti craftsmen to renovate the building as part of her dowry. The architectural style is a clear indication of Tibetan influence in Baltistan at the time.
The Mirs of Hunza abandoned the fort in 1945, and moved to a new palace down the hill. The fort started to decay and there was concern that it might possibly fall into ruin. Following a survey by the Royal Geographical Society of London, a restoration programme was initiated and supported by the Aga Khan Trust for Culture Historic Cities Support Programme. The programme was completed in 1996 and the fort is now a museum run by the Baltit Heritage Trust.
