The island of Koh Si Chang recalls its fleeting glory this month during its Centennial Memorial Day celebrations. The tiny island was once a getaway for Thai royalty, and Rama V (King Chulalongkorn) ordered the construction of a palace there to commemorate the place where his son was born. However, when French troops occupied the island in 1892 construction was put on hold. Eventually, the skeleton of the residence was moved to Bangkok, where it would become Vimanmek Mansion. The Memorial Day celebrations feature various activities and performances—the perfect excuse to visit this oft overlooked destination.
