The Roman wall that surrounds the city of Lugo is the only one in the world that is complete. For this reason and because of its mysterious beauty it has been declared a World Heritage Site.
Legend has it that the Romans built the wall to protect not a city but a forest; "Augustus' Holy Forest", Lucus Augusti in Latin, from which Lugo takes its name. Today the forest is a mystery, but the wall still stands, defying time and speaking to those who know how to listen.
