Find a spot to sit and watch the world go by at Plaza de la Font. If its well-trodden pathways could talk, this historic town square would have countless tales to tell.
You'll be spoiled for sightseeing choice in Old Town Tarragona. Plaza de la Font is a good place to kick off here, but there are lots of other worthwhile spots to consider.
