Champa
King
Started from the 17th century, Champa kings used title Paduka Seri Sultan in some occasions, a borrowed honorific from Muslim Malay rulers.
Cham port-cities
When French scholars arrived in the mid-19th century, they were impressed with Cham ruins, Cham urbanism, and medieval networks throughout the former kingdom. The middle-age densely populated areas of Tra Kieu and My Son were well connected by paved stone roads, bridges, urban ruins that were 16 feet high, rampart and stone citadel in a rectangle shape of 984 feet by 1640 feet, which hosted temples, fortified palaces, and resident structures, and were supplied by canals, irrigation projects, underground aqueducts and wells.
Fortresses and cities
Some of the network of wells that was used to provide fresh water to Cham and foreign ships still remains. Cham wells are recognisable by their square shape. They are still in use and provide fresh water even during times of drought.
