Chulalongkorn University, is a public and autonomous research university in Bangkok, Thailand. The university was originally founded during King Chulalongkorn's reign as a school for training royal pages and civil servants in 1899 (B.E. 2442) at the Grand Palace of Thailand. It was later established as a national university in 1917, making it the oldest institute of higher education in Thailand.
Rain trees are common on the university campus. They are associated with the cycle of student life. Fresh green leaves at beginning of the term represent the freshmen's naivete. As the tree produces slimy pods and sheds leaves, the ground beneath it becomes slippery, thus alerting students to prepare for examinations. If they walk carefully, they will not slip (pass examinations). If they walk heedlessly, they will slip and fall (fail examinations).
