Tarragona, Spain?
The vegetables are calçots, a sort of spring onion served roasted in the locality. The human pyramid are the Castellers de Barcelona, one of a number of teams that perform at a festival inTarragona in September. The Roman Amphitheatre shown is in Tarragona. The water splash is slightly confusing - it is not in Tarragona, but in Portaventura, Salou which is a couple of miles from Tarragona. Salou is probably where "stags and hens might misbehave". The herb which should give us a bit of a clue is tarragon.
