Situated at an altitude of 1851m on the left bank of river Beas, Naggar, is an ancient town which used to be the capital of Kullu State for around 1400 years. Providing excellent views of the surrounding mountains and forests, Naggar Castle is considered as one of the main attractions of this town. Presently a Heritage Hotel (run by HPDTC), the castle was built by Raja Sidhi Singh in the early sixteenth century. Constructed with locally sourced timber and rough-hewn stones and following the Kath-Kuni system of construction, Naggar castle is undoubtedly one of the magnificent historical edifices of Himachal Pradesh. Usage of alternate courses of stone masonry and wood without any cementing mortar is the key characteristic of Kath-Kuni construction system. The sheer weight of dry masonry and the roof in slate stones holds the structure down in place, which demonstrates superior resilience against earthquake and other climatic forces. Cantilevered balconies overlooking the central courtyard rest on the wooden beams fixed in the wood-and-stone walls. The historical temple Jagti Patt is located in the upper courtyard of the castle, which showcases rich display of wooden ornamentation. The castle exhibits a range of creative details in the form of exquisite wood carving, wooden joinery, surface articulation, door handles etc. Needless to say that the Naggar castle illustrates remarkable insights into traditional construction and indigenous knowledge.
