Vitoria is a large battlefield and, unfortunately, much changed since 1813. We spent a full day exploring it by car and managed to find many locations of interest, including Tres Puentes bridge with its picnic table.
Despite a lot of preparation we found Vitoria to be a difficult battlefield to explore, largely because of a large motorway right through the centre of the field, plus a large expansion of the city itself. We managed to find all of the locations in the southern part of the field, but as we got nearer to Vitoria itself it became increasingly difficult.
