The Palakkad Fort is said to have existed from very ancient times, but believed to be constructed in present form in 1766 A.D, but little is known of its early history. The local ruler, Palakkad Achchan, was originally a tributary of the Zamorin, but had become independent before the beginning of the eighteenth century. In 1757 he sent a deputation to Hyder Ali seeking help against an invasion threatened by the Zamorin. Hyder Ali seized upon the opportunity to gain possession of a strategically important location such as Palghat and from that time until 1790 the fort was continually in the hands of the Mysore Sultans or the British. It was first taken by the latter in 1768 when Colonel Wood captured it during his raid on Hyder Ali's fortresses, but it was retaken by Haider a few months later. It was recaptured by Colonel Fullarton in 1783, after a siege that lasted eleven days but was abandoned the following year. It later fell into the hands of the Zamorin’s troops. In 1790 it was finally captured by the British under Colonel Stuart. It was renovated and was used as a base for operations that ended with the storming of Srirangapatnam. The fort continued to be garrisoned until the middle of 19th century. In the early 1900s it was converted into a taluk office.
Current status
There is a large ground between the Fort and the Palakkad Town hall, known as Kota Maidanam. The ground is now used to stage cricket matches, exhibitions and public meetings. An open airauditorium called "Rappadi", currently under the preservation of the Archeological Survey of India, is also located within the spacious grounds of the Fort. Additionally, there is a children's park on one side of the Fort.
Interior
The Palakkad Special Sub Jail is also located within the fort. There is a small shrine dedicated to lord Hanuman known as Anjaneya Swamy temple, The temple is situated on the Eastern entrance of the fort, A figure of Anjaneya is carved in the inner side of the fort wall. The murthi of lord Anjaneya is south facing, while the lord himself is facing west. It is believed that Tipu and his warriors worshipped the lord to protect them from all enemies. A garden called Vatika-Shilavatika is maintained inside the court.
