In Catalan culture, the summer solstice (the shortest night of the year) is a very important day and is celebrated with the most iconic Barcelona summer festival called Sant Joan. In fact, it is a public holiday in the city, giving people the opportunity to celebrate the summer and the power of the sun, which is believed to bring fertility and wealth. Catalans believe in strengthening the power of the sun through fire so they celebrate the day of Sant Joan with fireworks and bonfires throughout the city. Many people will organise parties with friends and families to see the spectacular fireworks. As a tourist, we recommend heading to the beach, where many restaurants and bars will build extended seating in time for the festival to make sure that there is plenty of room to party and watch the fireworks.
