Tourists walk underneath the stone arches in Park Guell, designed by modernist architect Antonio Gaudi, in Barcelona October 1, 2014. The wealthy northeastern region of Catalonia last month dropped plans for a non-binding referendum on independence from Spain on Nov. 9 after a court declared such a vote against the constitution and had instead planned to hold a "consultation of citizens" on the same day. Although Spanish Prime Minister Mariano Rajoy and politicians in Catalonia have called for dialogue over the region's status after the initial referendum plans were abandoned, tensions are still simmering before the Nov. 9 alternative vote.
