One of my must-see sights for this recent visit to spain was the Roman Ruins at Mérida. I was impressed. We arrived close to mid-day and first enjoyed a menu del dia lunch at a place deeper in the town itself. Then wandered the ruins for the remainder of the afternoon. The amphitheater is more deteriorated than the theater but both are grand in scale and style. Then there are the temples, bridges, and a villa. In the villa, you find yourself walking on the mosaics which is a bit startling. Wouldn't permit that if it was my relic. Anyway, here's a video that gives an overview of what I saw.
