Porto Saint John Festival in Porto
Porto's Saint John festival, São João do Porto, transforms the city on the night of June twenty-third into twenty-fourth with fireworks over the Douro, street parties and the citywide ritual of tapping strangers on the head with small plastic hammers. Leeks, basil pots and paper hot-air balloons round out a set of customs unique among Portugal's midsummer saint festivals.
Every city in Portugal seems to claim its own version of the June saints' festivals, but Porto's São João has built an identity distinct enough from Lisbon's Santo António that the two are rarely confused by anyone who has experienced both.
