When Portugal will, next year, celebrate its fifty years of democracy, the main event will likely take place in the capital’s main plaza, commonly referred to as Terreiro do Paço (Palace Yard), one of the biggest in Europe, and the former seat of royal power. On one end, the plaza oversees the Tagus river. On the other, former King Carlos I and his heir prince Luís Filipe were assassinated in 1908.
