The survey, which is already underway, is the first major survey of this district since 1908, when ancient monuments were documented by French missionary A. H. Franke.

The Superintending Archaeologist, Chandigarh Circle, C. Dorje, said that about 50 monuments in that area are expected to be documented, complete with pictures, blueprints and maps. The survey is expected to be over in September, after which recommendations for carrying out conservation and preservation work where required will be put up.

With a large number of centuries old temples, monasteries, rock sculptures, rock carvings, stupas and forts dotting the mostly barren landscape, Spiti district is rich in cultural heritage. Just about every village has its own monastery.

The most significant monasteries in Spiti are at Lhaling, Kye, Pin, Nako and Tabo, which are associated with Buddhism and date back to the 10th century.

These monasteries, which were also educational centres, have a rich collection of antiques made of clay and metal as well as wall paintings, which throw a great deal of light on the lifestyle, culture and religious beliefs prevailing during that era.

The antiques include figures of deities, progenitors and weapons, besides ornaments and objects of daily use.

Another major archaeological monument is the fort at Tankar, built in the 16th century by local chieftains to fight against invasions.

Both, the Tankar Fort and the Kye monastery have a rich collection of weapons. The presence of weapons at Kye imply that the monks residing there had taken up arms to resist attacks.

Most of the land on which these monasteries are situated belongs to the concerned monument, and age-old activities including praying by Lama in the traditional manner, holding annual melas and celebrating the anniversary of religious leaders are still continuing.

These monasteries are generally self sustained as far as food crop is concerned.

While the fort and the monasteries at Nako and Lhaling are in urgent need of preservation and conservation, the Tabo monastery is a protected monument and is in good condition.
