Take Chua Chu Kang cemetery in Singapore, which is the only cemetery in the whole country still open for burial. Singapore is so small, geographically, that there is no affordable open land to create more cemeteries. The government passed a law in 1998 that says a person can only be buried there for fifteen years. When your fifteen years is up, your body is dug up, cremated, and stored in a columbarium (a building like a mausoleum, except for cremated remains).
