Among the four Stupas of Patan, the southern mound is known as Lagan Khel Stupa or Lagan Thura Stupa. It is the largest among the four, measuring 47.40 meters in diameter and 11.80 meters in height. The mound is crowned by a recent structure, a miniature cenotaph added on the top. The shrines of Tathagatas were presumable added in 1878; even as others were added to the eastern mound in 1846.An inscription tell us that on the western Stupa the Tathagatas were already in place by 1455.
