Konchogsum Lhakhang was built in the 6th century but was renovated in 1995, which accounts for its fresh look. It contained a large bell and it is believed that when this bell was rung it could be heard all the way in Lhasa in Tibet. During the 17th century a Tibetan Army tried to steal this bell but was too heavy and they dropped it and cracked it. It is now displayed at the National Museum in Paro.
The old lhakhang retains its central statue of Nampal Namse (Vairocana, one of the five Dhyani Buddhas). On Vairocana’s right are Chenresig and Longchem Rabjampa (founder of Tharpaling Goemba). On Vairocana’s left are statues of Guru Rinpoche and Pema Lingpa (said to be a reincarnation himself of Longchem Rabjampa).
There is a pedestal in the courtyard in front of the old lhakhang that used to be outside, but has now been internalised within the soaring walls of the new lhakhang. Upon this pedestal sat a large and ancient bell. It is said that when this bell was rung it could be heard all the way to Lhasa, Tibet.
The story goes that a 17th-century Tibetan army tried to steal the bell, but it was too heavy and they dropped it, cracking the bell. The fractured bell resides in the new Kudung Chorten Lhakhang in the upper level of the new building.
