Pandalam Palace, placed on the banks of Achankovil river, was home to the royal family of Pandalam. The palace is located in Pandalam at a distance of 10 km from the town of Adoor. The royal family of this palace enjoys a significant position in the history of Kerala. It is believed that they have descended from the Pandya kings of Madurai. Pandalam Palace carries not just historical importance, but a considerable religious magnitude as well. According to legends, Lord Ayyappa was born to the King of Pandalam.
There is a temple on the banks of Achankovil river which is dedicated to Lord Ayyappa. This temple bears a remarkable resemblance to the renowned Sabarimala Temple. Makaravilakku is the most prominent festival observed in the region. The sacred ornaments of Lord Ayyappa are carried from Pandalam Palace to Sabarimala as a grand procession three days prior to the festival. Divinity coupled with multihued festivities makes Pandalam Palace a popular destination for travellers.
