Answer
The Palakkad Fort, originally constructed in the 10th century, underwent several renovations over the centuries. Hyder Ali, the ruler of the Kingdom of Mysore, played a significant role in the fort's restoration in 1766. Under his command, extensive repairs and enhancements were undertaken, solidifying the fort's defensive capabilities and architectural grandeur. Hyder Ali's contributions ensured the continued strategic importance of the Palakkad Fort as a stronghold in the region.
