When the Thailand Tobacco Monopoly moved all its factory operations to Chiang Rai in 2008, the lake and some adjoining land that were part of its compound, previously enjoying semi-wild vegetation, were turned into a public park. Many splendid old rain trees were cut down in order to landscape the park, in which young trees were planted instead. Adjoining the Queen Sirikit National Convention Centre, it is a neat park with dedicated cycling and walking paths, fixed exercise equipment and several monuments.
