Formigas

The Formigas Islet and Dollabarat Reef, sometimes referred to as the Formigas Bank, are a remote group of rock outcroppings in the eastern group of the Azores archipelago, an autonomous region of Portugal. The bank is located 43 kilometres (27 mi) northeast of Santa Maria Island and southeast of São Miguel Island covering a surface area of approximately 9 square kilometres (3.5 sq mi). The bank is only disturbed by a lighthouse located on the largest mound.
