When you come to Guoye Village, besides the sunrise, you should not miss the Gig Guoye columnar basalt.  This majestic basalt cliff was the pentagon and hexagonal rock column rupture called as columnar joint formed by rocks as the seabed magma cools and contracts when the topography rose.
Due to the special terrain of Penghu, there is much basalt. On the way to the Siaomen Whale Hole scenic spot in Shiyu Village, you can also see such terrain, but because the whole Gig Guoye basalt cliff in this area is columnar joint and is high enough, it forms a very special landscape. And every time after heavy rain, the concave ground in front of the basalt is filled with rainwater the entire towering cliffs are reflected in the water and forms a very unique and amazing picture, which attracts many people to come to take pictures. It is one of the special natural landscapes of Shiyu Village.
In the past, it was a private land close to the Gig Guoye basalt columns, and the landowners sold the land at a very low price to someone, who originally scheduled to build a holiday villa on this land. However, once the construction began, the Gig Guoye basalt area next to this terrain must be damaged, so the county government magistrate Mr. Wang Kan-Fa decided to buy back this land after a survey, and then this rare wonder of basalt was preserved. So, next time when you came here to enjoy the beauty of Gig Guoye basalt column, do not forget the cries of people who advocated culture and geology protection, and the Penghu County Government’s determination to emphasis geological and cultural assets of course, we shall express our gratitude to the person who agreed to give up this land. After all, without these people’s efforts, we would never appreciate this world-class geological and cultural asset!
