This sculpture, called Time's Radiograph, was created by Panaite Chifu of Romania in 2005, as part of that year's Hualien International Stone Sculpture Festival. It's on permanent display near the border between Hualien and Taitung counties, on a vantage point which overlooks the Pacific Ocean.
Public art isn't uncommon in Taiwan. In 1992, a law was passed which stipulated at least 1% of the budget of major building projects should be devoted to beautifying the surrounding environment with artworks. Several MRT stations in Taipei and Kaohsiung contain sculptures or installations; elevated stations in the latter are also striking pieces of architecture.
