On the high square plinth rests a three tiered drum in cylindrical form measuring 9 meters leaving an approx. 5 meters wide ambulatory. Amluk Dara StupaThe stupa is further surmounted by a hemispherical dome measuring 7m in height. The drum on which the hemispherical dome rests has a diameter of 21m, probably being the largest in the Ilam valley. The drum is divided by a bold cornice supported by brackets at intervals of 0.30cm. A second cornice projecting farther runs below the bottom course of the dome. The height of the stupa from the floor level on the ground up to the existing top of the dome measures 20 meters. The stupa has a flight of ascending step on the north, which is 04.26m wide connecting the pradakshina patha on the ground level with the ambulatory passage on the top of the plinth. The pradakshina patha on the top of the plinth is approached by another step 03.65m wide which leads to the third pradakishna patha. It is only here that a hole measuring 04.57m deep was dug in the drum to reach the relic chamber. The entire stupa building from base to the top shows a remarkable fine, semi-ashler masonry, preserving good stretches of the architectural decoration, typical of the Gandahara valley during the period Kushanas.
