Tanjung Tuan or Cape Rachado (as named by the Portuguese, meaning Broken Cape) is an exclave of the state of Malacca, Malaysia, adjacent to the town of Port Dickson,Negeri Sembilan.
The cape is well known for the Cape Rachado Lighthouse facing the Strait of Malacca. The coastal area off the cape is famous as the site of the naval Battle of Cape Rachado in 1606, between the Dutch VOC and Portuguese fleets. The battle was the opening act for the series of conflicts between the Dutch-Johor coalition and Portuguese Malacca that ultimately ended with the Portuguese surrender of the city and fort of Malacca to the VOC in 1641.
After Portugal conquered Malacca in 1511, the Portuguese wanted to build a lighthouse to guide its ships. Tanjung Tuan was chosen and the cape was named Cape Rachado by them. Subsequently, a lighthouse was built between 1528 and 1529. As Malacca switched hands to the Dutch and later to the British in 1641 and 1824 respectively, so too did the possession of the structure.
In 1921, the area was gazetted as a permanent forest reserve under (No.Warta : 2066 bertarikh 23 Disember, 1921) with 809,700 square metres under the name of Hutan Simpanan Cape Rachado. However, in 1969 an area of 161,900 square metres was degazetted from the permanent forest reserve status for the purpose of public use (No.Warta : 328 bertarikh 25 Disember, 1969).
On 5 January 1971, The rest of the 607,000 square metres of the Cape Rachado forest reserves was gazetted as a wildlife sanctuary under the jurisdiction of PERHILITAN (forestry and wildlife protection department) under M.P.U.5 and PG No: 85 under the Birds and Wild Life Protection Ordinance, 1955 (Ordinan Perlindungan Binatang-Binatang Liar dan Burung-Burung, 1955).
On 16 April 1996, a company (Dataran Baiduri Sdn Bhd) was assigned to commercially develop the park.
