The monumental statue of Jatayu resting high up the hill catches your attention even from a far on your way to Chadayamangalam in Kollam district. Jatayu is a legendary bird from the Indian epic Ramayana. The giant sculpture of Jatayu is 200 feet long, 150 feet broad, and 70 feet high with a floor area of 15,000 square feet. That makes it the world's biggest bird sculpture."
