Close to the Retezat mountains and in the part of Romania which was Dacia are the ruins of Ulpia Triana Sarmizegetusa. Find your way there on the local bus from Santamaria-Orlea, hop off when the locals tell you because there are no big signposts and wander around the ruins of the outpost of the IVth legion.You will be enthralled by its size and you will find there every building that a Roman settlement should have. If that is not enough just a short walk down country lanes brings you to beautiful Densus church, a UNESCO World Heritage site. Cobbled together from stones probably taken from a Roman mausoleum the church contains frescoes, paintings from the 15th century oh, and those Roman carvings set into the outside walls!
