Chetwai Lighthouse is about 8 Km from the famous Guruvayoor Temple. Guruvayoor town is connected to Trichur on Shoranur- Cochin section by Rail and Road. Chetwai Lighthouse is linked to Guruvayoor by a metalled road via Chavakkad. town.
Chetwai (locally Chettuva) is a village on Chettuva creek, about 4 km south-east from LH. It draws its reference in 18th century as an important fort and garrison of Zamorin the ruler of Malabar From the fort of Chetwai the Zamorin attacked Cochin and repulsed Dutch attacks. However Zamorin could not defeat the forces of Hyder Ali of Mysore who conquered the whole of Malabar in 1765-66. The Zamorins had ruled independently for 250 years and the defeat at the hands of Hyder Ali was so shocking that the last Zomorin committed suicide by putting his palace on fire.
The region was rich in opium production. The British traders had established a branch of their Tellicherry factory here. The British East India co occupied the region in the early 19th century. The region became part of Kerala in Nov 1956.
In the vicinity of Chetwai Lighthouse the coast is low, sandy and fringed with coconut trees. There did not exist any lighthouse earlier to the present one at Chetwai. An unlighted beacon 6 m high painted black and white erected on North side at the entrance of the backwaters, was the only identification mark.
The work on the construction of this Lighthouse Tower was completed in 1985-86 and the PRB-42 equipment supplied by M/s. Asia Nav. Aids, New Delhi, was installed and commissioned into service on 29th September 1986.Major changes were effected as the `C’ type lamps were replaced by 30V 200W `D’ type sealed beam lamps and a lantern house was also installed on the lighthouse on 30th April 2003. |
