Bekal Fort is the largest fort in the state of Kerala, India, spreading over 40 acres (160,000 m2).An important features of this fort are the water-tank with its flight of steps, the tunnel opening towards the south, the magazine for keeping ammunition and the broad and wide steps leading to the Observation Tower which is a rarity. From there one has ample view of towns in the vicinity like Kanhangad, Pallikare, Bekal, Kottikkulam, Uduma etc.
This observation center had strategic significance in discovering even the smallest movements of the enemy and ascertaining safety of the Fort.
The Fort appears to have been built up from the sea since almost three fourth of its exteriors is drenched and the waves continually stroke the citadel. The Mukhyaprana Temple of Hanuman and the ancient Muslim Mosque nearby bear testimony to the age-old religious harmony that prevailed in the area. The zigzag entrance and the trenches around the fort show the defense strategy inherent in the fort.
