The bollards some of which are still in satisfactory condition was made of teak. Three Tamil-Brahmi scripts were also found in the Pattanam excavations. The last Tamil-Brahmi script (dated to c. 2nd century AD, probably reading "a-ma-na", meaning "a Jaina" in Tamil) was found on a pot-rim at Pattanam. If the rendering and the meaning is not mistaken, it establishes that Jainism was prevalent on the Malabar Coast at least from the 2nd century. This is for the first time the excavators are getting direct evidence relating to a religious system in ancient Kerala. Muziris Heritage Project is a tourism venture by Tourism Department of Kerala to reinstate the historical and cultural significance of Muziris. The idea of the project came after the extensive excavations and discoveries at Pattanam by Kerala Council for Historical Research. The project also covers various other historically significant sites and monuments in central Kerala. The nearby site of Kottapuram, a 16th-century fort, was also excavated (from May 2010) as part of the Muziris Heritage Project.
