Taxila has its mammoth worth in Pakistani heritage due to its archeological ambience. Right from the 1st century A.D. and from the primordial Neolithic tumulus of Saraikala to the ramparts of Sirkap, (200 B.C.) and then to the city of Sirsukh, Taxila exemplifies the various phases in the development of a city on the Indus. Taxila, largely influenced by Persia, Greece and Central Asia, happened to be the significant Buddhist centre of learning from 5th century B.C. to the 2nd century A.D. In 1980, the World Heritage List got Taxila inscribed on it.
The Buddhist establishments were very much there in that era of Taxila, which is why the remains of the same associated with this historical city exist on several kilometers on all sides. The archeological digging taken place in the valley on larger scale did wonders by exposing the colossal areas of ancient structures. And most of these structures are constructed in lime stonework. The growth of plants, vegetation, weeds, lichen, fungus, mosses, atmospheric pollution etc are happening massively there and these things are undoubtedly responsible for the worsening of the precious heritage and still it poses the chief problems in protecting this legacy.
UNESCO took the giant step to protect this heritage and sponsored a workshop where the concerned officials got passed on the training sessions to deal with these problematic issues. Recently Taxila valley has emerged as the hub of industrial activities and a number of industrial set-ups can be seen there in the valley. In addition to this problem of increasing industries there, the ever-increasing population too poses the new threat to the monuments there.
Sensing these problems, the Government of Pakistan has now taken a step by establishing a protected zone that deals with all the significant areas of archaeological interest. But sadly, the restrictions imposed in the protected zone have not been much effectual so far. In the open area of the Bhir Mound, a sports stadium was constructed last year but the government has now issued the orders to demolish it.
