Masjid Tengkera (Tranquerah), Melaka
A three-century-old mosque with a sultan's grave! Built around 1728 in the same Sumatran-Javanese style as Kampung Hulu, Masjid Tengkera holds the tomb of Sultan Hussein Shah of Johor, who signed the 1819 treaty ceding Singapore to the British. A quiet, deeply historic corner of Melaka that most visitors miss.
