This nomination was initiated as the serial nomination where both states applied for it as an UNESCO world heritage site based on the importance of the Straits of Melaka as an crucial world trade routes linking the west and east thus creating some important cities along the Straits of Melaka. The recognition is given by the aesthetic culture of the two cities that include cultural amalgamation of Portuguese, Dutch, Arabic, Chinese and English with the local Malay community. This culture is not only viewed from the aspect of intangible heritage but also highlighted the historical buildings since more than 500 years.
