This Roman archway in Beja

This Roman archway beside the castle is not exactly a show-stopping sight, but it’s valuable enough to be listed as a Portuguese National Monument. If you’re an antiquarian you might also get frissons knowing these stones have conducted people in and out of the town for more than 1,700 years. It is wedged between the old town ramparts and the medieval walls of the castle and was discovered among the ruins of a gate that had been torn down in the 16th century. When archaeologists realised its value it was reconstructed and protected.
