Inside the Alchi Gompa is Alchi's most celebrated temple Sum-tsek. Standing on the left of Du-Khang, this three storey mud structure has three enormous figures of four armed Bodhisattvas. These Bodhisattvas are placed in alcove in the side and far walls while the middle part of the floor is occupied by a 14 1/2 feet figure of Maitreya Buddha with his upper right hand in abhaymudra. To his left and right is the white Avalokiteshvara and a figure of Manjushri in a vitarkamudra (gesture of explanation) respectively.
