Amboori was inhabited by members of the Kanikar tribe since time immemorial. Around 1200 members are still living here with all cooperation to new settlers. During the year 1729, a princely state came up in the name of Thiruvithamcoor or Travencore under the rule of King Marthandavarma. The King had several enemies like "Ettuveettil Pillamar", who was trying to eliminate him. To escape from them, the King stayed in various places like Ammatha, Pathukaani, Kottamanpuram, and Meenmutty in Neyyar River belt. At that time, the Kani tribe was taking care of his safety and security. At a time, the tribe took him to a large boulder called the Dravyappara (the treasure rock), which is approximately 700 ft from its base and 1500 ft above sea level.
