Muchiri, commonly anglicized as Muziris was an ancient harbour and an urban centre on the Malabar Coast. Muziris found mention in the Periplus of the Erythraean Sea, the bardic Tamil poems and a number of classical sources. It was the major ancient port city of Cheras. The exact location of Muziris has been a matter of dispute among historians and archaeologists. However, excavations since 2004 at Pattanam in Ernakulam district of Kerala have led some experts to suggesting the hypothesis that the city was located just there. It was an important trading port for Christian and Muslim merchants arriving from other countries.
