Tarragona–the Emperor Augustus's favorite winter resort–had arguably the finest ampitheater in Roman Iberia. The remains of the amphitheater, built in the 2nd century AD for gladiatorial and other contests, have a spectacular view of the sea. You're free to wander through the access tunnels and along the tiers of seats. In the center of the theater are the remains of two superimposed churches, the earlier of which was a Visigothic basilica built to mark the bloody martyrdom of St. Fructuós and his deacons in AD 259. €11.05 buys a combination ticket card valid for all Tarragona archeological museums and sites.
