Northern Luzon is home to some of the most breathtaking landscapes and iconic landmarks in the Philippines. Among these are two engineering marvels. They not only captivate the eyes but also reflect the ingenuity and sustainable vision of the region: the Patapat Viaduct and the Bangui Windmills. We had a chance to see them a day before our Visita Iglesia in Ilocos. So if you’re planning a road trip to Ilocos Norte, these two stops should be at the top of your list.
