At Harwan in Srinagar, a very important Buddhist site having stupas was discovered by R.C. Kak in 1925 on a slope of a mountain. Sir Aurl Stein identifies ‘Harwan’ with Shadarhadvana (grove of six saints), a locality mentioned in Rajatarangini.

As we see in the pictures, the walls were constructed in what has been called “diaper rubble style,” wherein a number of large undressed boulders are placed in one row with intervening spaces filled with smaller stones.

Great photos and very interesting. BUT how about some pertinent details? When does it date from? What school was it? Do we know anything about the monks and their Masters?
