Pullumedu's historical significance is tied to the Sabarimala Ayyappan Temple. During the Makaravilakku festival, the Makarajyothi, a bright light, appears on the Ponnambalamedu hill, which is visible from Pullumedu. This celestial event is considered sacred by devotees. Beyond its religious connection, the area has traditionally been inhabited by tribal communities who have lived in harmony with nature. The region's history is thus intertwined with both religious beliefs and the indigenous people's close relationship with the natural environment.
