The New Lighthouse was constructed to replace the older, less effective lighthouse located near the Shore Temple. While the old lighthouse served its purpose for a time, the growing maritime traffic and the need for improved navigational aids led to the construction of this modern structure. The New Lighthouse utilizes advanced technology to emit a powerful beam of light, ensuring the safe passage of ships along the coast. Its construction reflects the ongoing efforts to preserve maritime safety and support the fishing industry in the region. While not as ancient as the other historical monuments in Mahabalipuram, the New Lighthouse plays a vital role in the town's present and future.
