Biliran Watchtower
Philippines
The 186th tallest tower in the world
The Biliran Watchtower, also known as Nasunugan Watchtower, is a watchtower ruin located in Biliran, Philippines. Built in 1765 under the initiative of Filipino priest Gaspar Ignacio de Guevara, the watchtower was used to watch Biliran's coast for Muslim raids. In 1774, the raiders attacked and burned the local settlement, including the watchtower. In 2000, the watchtower was reconstructed using its original materials. In 2008, the National Historical Institute (now the National Historical Commission of the Philippines) installed a historical marker on the watchtower.
