The Monument to the Peaceful Liberation of Tibet was unveiled in the Potala Square in May 2002 to celebrate the 51st anniversary of the Seventeen Point Agreement for the Peaceful Liberation of Tibet, and the work in the development of the autonomous region since then. The 37-metre-high concrete monument is shaped as an abstract Mount Everest and its name is engraved with the calligraphy of former president Jiang Zemin, while an inscription describes the socioeconomic development experienced in Tibet in the past fifty years.
