Situated in the North East of the island of Mallorca, Spain on a gorgeous beach named Platja de Muro lies Torre d'enfilació. It features mysterious Egyptian-like obelisks that were said to have been built by the Spanish Navy just after the Spanish Guerra Civil. There 28 towers in total that were used for spotting submarines off the coast until better technologies made them obsolete. Now they are quite the neat tourist attraction, along with the hiking trails located throughout the sand dunes. The dunes are home to a unique ecosystem that has an interesting pine forest.
