Distribution and types of gravestones show that styles of Muslim funerary markers changed significantly over the 15th and 16th centuries. Almost all graves that we believe date to the 15th century (in blue) are located on the elevated headland in cluster 10. The yellow markers are all types that are associated with the Aceh Sultanate and date from the mid-16th century onward. Image courtesy of Y. Descatoire (Earth Observatory of Singapore, Singapore).
