Barcelona walk idle, muted.
The Gothic Quarter is the part of Barcelona that makes least sense from a map and most sense on foot. Lanes fold back on themselves, open into a square with a fountain and four palm trees, and close again into something two metres wide. The city around it is on a grid; this bit predates the grid by centuries and behaves accordingly. These walks stay inside that contrast, at pavement level, with the sound of the street left intact.
