Halcyon Castle was built in the 1930's in the city of Travancore, state of Kerala, India. Originally the castle was built by Sri Rama Varma Valia Koil Thampuran, consort of Regent Maharani Sethu Lakshmi Bayi, and it served as a summer retreat. This royal palace has been converted into a deluxe hotel. The castle became disputed when the ITDC (India Tourism Developement Corporation) who was running the hotel sold out the hotel to a private Hotel resort group. The government of Kerala is trying to take the possession of the castle by claiming it as a heritage site, although, not without challenge by the hotel group.
