The thin white Bhimsen Tower; also called Dharahara or Bhimsen Stambha (stambha meaning 'pillar') collpased during the 2015 earhquake that shook Nepal. The 60 metre high tower was built in 1824 by Prime Minister Bhimsen Thapa as a watchtower; the construction was based more on a whim than military necessity. Originally there were two towers; but the other collapsed in 1832. Pictures From Asia Rainer Krack
