‘Slow Down, Stop, and Stay’ introduces a surprise element in order to temporarily change the current dynamics and avoid skate monoculture in Plaça dels Àngels. We want the skaters to thrive along with other kinds of uses and activities. ‘Slow Down, Stop, and Stay’ is an infrastructure to prompt naturally occurring public space appropriation activities on the part of the local residents and users of the square. It is an open system that will activate potential reactions, opening the eyes of the users to what the square might really be, rather than what it is now. The outcome hopefully will be a trigger for possible new types of uses and behaviors that will enrich this relevant Barcelona public space.
