Known by the innocuous moniker La Rotonda del Mar or The Rotunda By The Sea, the surprisingly sinister installation is the work of Guadalajaran sculptor, Alejandro Colunga. The eight bronze thrones, unveiled at the end of 1996, are positioned at irregular intervals around a stone circle, with the sea lapping right up to the edge. The tall, amorphous chairs are topped with impressionistic sea creatures like an octopus and a seahorse, that seem to be parts of the thrones themselves. Many of the seats are also supported by legs that end in claws or organic “feet,” making them seem like strange, eldritch monuments. They seem to have been designed with whimsy in mind, but the dark, Lovecraftian influences can’t help but shine through.
