Kosapet is a locality in Chennai, situated near Purasawalkam. The name is a corruption of Kuyavar Pettai (potter's locality) that originated due to the concentration of potters and artisans in this area.
The Kuyavars (the potter's) of Kosapet have been engaged in the profession for generations.
Story 2: Purasawalkam
Purasawalkam got its name from Purasu or Flame of the Forest. The area was once known as Purasavanam, possibly due to the abundance of the Purasu trees that used to be here. The tree is also called Palasu and Murukku. The wood of the tree was used in oil presses in the old days. Unfortunately, it is believed that there is only one Purasai tree here today. It is the sacred tree of the Gangadeeswarar temple, the sthala virutcham and, being inside its precincts, is well protected.
