Notable among other monuments such as the twelfth century Romanesque churches of Santa María del Campo and Santiago and it has also been used to build the pedestal of Hercules´ Tower, this is a majestic lighthouse in A Coruña city, it was declared World Heritage by UNESCO in 2 009. San Pedro leucogranite is part of the pavement of the main tourist streets of A Coruña city (Calle Real and Cantones, to name some of the most popular).
