Palma: The oscillating core of a suspended periphery. An imagologic approach …

Abstract: In the first decades of the twentieth century Palma emerged as a city worth visiting with a promising network of hotels and organised tours. Palma became an urban playground for British bohemians, artists, expatriates, and socialites. Their notion of leisure and pleasure (on a faraway island) provided the leitmotiv for the years to come. The purpose of this paper is to inspect the ex…
