Jardin du Belvédère

This guide to Jardin du Belvedere in Lyon centers on an unsolvable crossword engraved into the steel seat of one of six chairs carved by Quebec sculptor Michel Goulet, installed in 2000 to mark twenty years of partnership between Lyon and Montreal. It follows how the grid was built long distance, with a Canadian crossword setter and a French writer trading clues about both cities until their answers locked together. Every other chair on the terrace carries an inscription about looking, remembering or imagining.
