Pattazhy, also Pattazhi is a village located in Pathanapuram taluk in the eastern part of the Kollam District, Kerala state, India. It is best known as the site of an ancient Bhagavathy temple, Pattazhy Devi Temple.
Pattazy is a part of Pathanapuram Block Panchayat andruled by pattazhy panjayath Kollam district Panchayat.
The name Pattazhy has an uncertain etymology. Pattazhy may stem from an imperfect Malayalam portmanteau fusing Patt ("Soft") and Aazhy ("Ocean"). Thus the word Pattazhy represents the compassion and affection of Pattazhy Devi to her beloved devotees and depth of her grace. The name Pattazhy may have also derived from the word Bhattarika which means a virtuous and pious woman.
Pattazhy is a village situated in Pathanapuram Taluk of Kollam District in Kerala. The land of Pattazhy comprising two panchayat areas (Pattazhy and Pattazhy vadakekara) was given as a gift to Pattazhy Devi by the King of Travancore for the help and shelter given in the fierce fight against the king of Kayamkulam. When the king was extending his kingdom by winning war with the neighboring kingdoms with the help of Ramayyan Dalawa, Kambithan, a hardcore worshipper of Pattazhy Devi helped the king to take over Kayamkulam Kingdom. As a symbol of his gratitude the king ordered to let Pattazhy be named and dedicated to Devi by issuing a royal order. The annual festival at Pattazhy Devi Temple is one of the famous temple festivals in central Travancore. The Kumbhathiruvathira and Meenathiruvathira were the famous festivals of Pattazhy. The festival is known for Kambam (fire works), Aalpindi Vilakku Ezhunnallathu (Procession of small structure made out of plantain kernel and germinating leaves of coconut tree with numerous lamps on it), Ponnin Thirumudi (Devi's idol carved out of pure gold and rare precious stones) Ezhunnallathu.
Pattazhy also got a place in the Guinness Book of world records for the 'Longest bamboo'.
