For adventure seekers and history buffs alike, the waters of San Esteban, Ilocos Sur, hold a secret beneath the waves. While the town is famous for its coastal watchtower and “heavenly” grotto, its most thrilling attraction lies in the depths of the West Philippine Sea: the San Esteban World War II Wreck. The History: A Relic of the Great War The waters of Ilocos Sur were a strategic theater during the closing years of World War II. As the USAFIP-NL (United States Armed Forces in the Philippines – Northern Luzon) and local guerrillas pushed to liberate the north, several Japanese supply ships and transport vessels were intercepted by Allied air and sea power. The Dive Site: Exploring the Depths San Esteban is becoming a premier destination for Scuba Diving in Northern Luzon because of this wreck. The Landing Site: Liberation History The shoreline near the dive site is equally historic. Known as the San Esteban Landing Site, this stretch of beach was used by liberating forces and local resistance groups to receive supplies and coordinate movements against the retreating Japanese forces in the mountains of Ilocos. Today, it is a peaceful area, often used by local fishermen, but a small plaque or local markers often remind visitors of the blood and grit that once defined this coast. How to Get There & Dive If you are coming from Candon City or Vigan, the dive site is easily accessible via the San Esteban town proper. Traveler’s Tip: Because of the depth and the potential for currents, this is generally considered an Advanced Open Water dive. However, even if you aren’t a diver, visiting the landing site at sunset offers a poignant moment to reflect on the history resting just beneath the horizon.

In the quiet coastal town of San Esteban, Ilocos Sur, a unique spiritual landmark stands against the backdrop of the West Philippine Sea. Known locally as the Grotto of San Esteban, this site features a statue of the Virgin Mary perched atop a massive, dark rock that has long been the subject of local legend. The “Stone from Heaven” According to local folklore, the great rock upon which the image of Mama Mary stands is not a natural coastal formation but a meteorite—a “stone from heaven” that fell to earth generations ago. Spiritual Significance and History San Esteban has a deep connection to its landscape; even its name is rooted in the “abundance of stones” found along its coastal mountains. How to Get There The Grotto is located along the scenic coastline of San Esteban, near the popular Bateria Watchtower. Traveler’s Note To truly experience the magic of the “Stone from Heaven,” visit during the late afternoon. As the sun dips below the horizon, the grotto becomes one of the most photographed and serene spots in Ilocos Sur, perfectly blending the town’s mysterious legends with its deep-seated faith.

Standing guard over the serene coastline of Ilocos Sur, the San Esteban Moro Watchtower (locally known as Bateria) is a silent witness to centuries of maritime history. While often overshadowed by the larger belfries of Vigan or Bantay, this coral-stone sentinel offers a raw, rugged beauty that is a must-visit for any traveler exploring the 2nd District. The Sentinel of the Sea: A Brief History The San Esteban Watchtower is one of the many coastal fortifications built along the Ilocos coastline during the Spanish Colonial Era. The Purpose: Defense and Early Warning The name “Moro Watchtower” stems from its primary function: guarding against pirate raids. During the Spanish period, “Moro” pirates from the southern seas would often raid northern coastal towns for supplies and captives. What to Expect Today Unlike the restored towers in other provinces, the San Esteban Bateria retains a weathered, authentic charm. How to Get There San Esteban is conveniently located along the MacArthur Highway, making it an easy pitstop between Candon City and Vigan. Traveler’s Tip: Combine your visit with a trip to the San Esteban Fish Sanctuary or the nearby Apatot Beach.
