Explanation:

Conceived at a cost of Rs 94 crore, Kerala’s Muziris Heritage Project is billed as India’s largest heritage conservation plan. Kodungallur, just over an hour’s drive from Kochi in central Kerala, stands at the very spot where an ancient port city by the name of Muziris stood, which dates back as early as 3000 BC. The port was the most important trading hub of the Cheras.
A Tamil poem from the Sangam period describes the port, “Here lies the thriving town of Muchiri, where the beautiful large ships of the Yavana come, bringing gold, splashing the white foam on the waters of the Periyar, and then return laden with pepper. Here the music of the surging sea never ceases, and the great king presents to visitors the rare products of sea and mountain.”
