The history of Kodikkarai is intertwined with its geographical significance as a prominent cape jutting into the Palk Strait. Historically, it served as a crucial landmark for maritime navigation. The Chola dynasty, known for their naval prowess, likely utilized the area. Later, the British recognized its strategic importance and established a lighthouse to guide ships. The area also holds historical significance due to its proximity to Sri Lanka and its role in various trade routes. Over time, the region evolved from a vital navigational point to a protected wildlife sanctuary, preserving its natural beauty and biodiversity. The lighthouse, still standing, serves as a reminder of its maritime past.
