The Digha Lighthouse was established to aid navigation for ships and fishing vessels traversing the Bay of Bengal. It plays a crucial role in maritime safety by emitting a beam of light that guides ships, especially during the night and in adverse weather conditions. While the exact year of its construction may vary depending on the source, it has been a fixture of Digha's landscape for several decades, serving as a vital navigational tool. Over time, it has also become a popular tourist attraction, drawing visitors who are keen to enjoy the views from its summit. The lighthouse has undergone upgrades and maintenance to ensure its continued functionality and safety. It stands as a testament to Digha's maritime history and its importance as a coastal town.
