"The Riga Opera Festival, founded in 1998 as the first festival of its size and scale in Eastern Europe, has already become a valuable tradition." That's how they discribe this festival on their event-page. But it's not only a tradition. It's for all the people who love the opera. The Riga Opera Festival is every summer at the end of the latvian National Opera's performance season and has different themes every year. So if you love opera, thats your point.
