Bekal Fort is the biggest fort in Kerala, spreading over forty acres. The important features of this fort are the 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 centre had strategic significance in finding out 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 stroke the citadel. The Hanuman temple and the ancient Muslim Mosque nearby hold 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 connected with the fort.

Unlike most other Indian Forts, Bekal fort was not a center of administration for no remains of a palace are found within the fort. Arguably the fort was built exclusively for fulfilling the defense requirements. The holes on the outer walls of the fort are specially designed to defend the fort effectively. The holes at top are meant for aiming at the farthest points; the holes below are meant for hitting when the enemy is nearer and the holes underneath facilitate attacking when the enemy is very near to the fort. This is a remarkable evidence of medieval technology in defense strategy.
