Pedra Furada (Santa Catarina)
Pedra Furada (Portuguese pronunciation: [ˈpɛdɾɐ fuˈɾadɐ], literally Drilled Stone) is a naturally formed rock arch located in the municipality of Urubici, state of Santa Catarina, Southern Brazil.

It can be spotted from the summit of a mountain named Morro da Igreja.
Yasser Rabello (The Alchemist) made a remarkable discovery about this monument in his channel on YouTube. He claims it is an ancient monument, because It is a portal carved in a stone and it is aligned with the Ley lines of other portals that includes Stonehenge (45 degrees), AramuMuru and PumaPunku. It contains enigmatic inscriptions carved in the walls of this stone, like the ones found on Pedra Ingá (Ingá stone) with complex mathematical codes embedded on it.
