Godavaya was an important port during the time of the ancient Sinhalese kingdom, which existed from around the 6th century BC to the 13th century AD. The port was used to trade with the rest of the Indian Ocean region, including India, China, and the Middle East. The ancient Sinhalese kingdom was known for its maritime trade and seafaring culture, and Godavaya was a major hub of this activity.

The port of Godavaya was an important center for the export of spices, precious stones, and other valuable goods. The port also played a significant role in the spread of Buddhism in Sri Lanka and the rest of Southeast Asia. Many Buddhist monks and scholars travelled through Godavaya, spreading the teachings of the Buddha and exchanging knowledge and ideas with other cultures.

In addition to its commercial and cultural significance, Godavaya was also a strategic location for military and political purposes. The port was used as a base for the Sinhalese navy, and played a key role in many battles and conflicts throughout the history of Sri Lanka.
