"In its day—thankfully, we’re talking Roman times—Tarragona’s amphitheater was the scene of bloody, spear-launching battles between gladiators. There were even public executions. Today, it’s more about taking aim at the neighboring sea view than one of your compatriots, but the site is steeped in gruesome history. These days, around two thirds of the seating complex remains, but you can wander into the action pit and under the archways where fighters would have unleashed their battle charge. The backdrop of the glistening Mediterranean adds a special (less gory) touch." - Gemma Askham,Jessica Benavides Canepa
