Using this free app for your phone or tablet, you can experience the city in the past.
Perhaps the closest you’ll be able to get to actually being in Tarraco during the Roman era is this new augmented reality app, that shows you how the locations you’re in would have once looked.
The Imageen app for mobile phones and tablets gives you an ‘in situ’ immersion by placing video recreations over the top of your camera view of monuments and spaces in Tarragona. Hold your phone up to the monument you’re standing in front of and watch chariots and Roman soldiers go past.
The app is free to download and has instructions on how you can use it around the city.
