Kollam (IPA: [koɭɭam]) or Quilon (Coulão), formerly Desinganadu, is an old seaport and city on the Laccadive Sea coast in Kerala, India on Ashtamudi Lake. Kollam has had a strong commercial reputation since the days of the Phoenicians and Romans. Fed by the Chinese trade, it was mentioned by Ibn Battuta in the 14th century as one of the five Indian ports he had seen during the course of his twenty-four year travels. Desinganadu's rajas exchanged embassies with Chinese rulers while there was a flourishing Chinese settlement at Kollam. In the 9th Century, on his way to Canton, China, Persian merchant Sulaiman al-Tajir found Kollam to be the only port in India visited by huge Chinese junks.
