Climb the Spiral Staircase for 360-Degree Views: The ultimate highlight of a visit to Thangassery is climbing the 200-plus steps of the internal winding spiral staircase. As you ascend the historic stone tower, the air grows cooler until you emerge onto the breezy, railed outdoor observation deck. From this incredible vantage point, you are treated to a stunning, bird’s-eye view of the crashing waves of the Arabian Sea, the sprawling Thangassery breakwater harbor, and the endless green canopy of Kollam’s coconut plantations.

Inspect the Vintage Optic and Lantern Room: For engineering and history enthusiasts, the lantern room at the summit houses a magnificent, vintage second-order Fresnel lens system. Visitors can get a close-up look at the intricate, hand-polished glass prisms that have focused and thrown light across the ocean for generations. Learning about the transition from traditional oil lamps to modern automated LED systems offers a rare glimpse into the evolution of global seafaring technology.

Explore the Ruins of the Dutch and Portuguese Forts: Directly surrounding the lighthouse precinct are the atmospheric, vine-covered ruins of Fort Thomas and the old Dutch cemetery. Built by the Portuguese in 1518 AD, the remaining seaside walls, bastions, and arches of the fort sit right on the cliff’s edge. Walking through these weathered stone structures allows you to step back in time and imagine the era when European armada fleets fought for control of the Malabar spice trade.

Walk the Massive Thangassery Breakwater Jetty: Extending nearly 3 kilometers right into the ocean from the foot of the lighthouse area is the massive Thangassery breakwater system. Constructed of giant, interlocking concrete tetrapods, this seaside pier is a favorite spot for evening walks. It allows you to walk far out into the water, with the crashing surf on one side and the calm fishing harbor on the other, providing the perfect angle to photograph the towering lighthouse against a setting sun.
