Wow, an extreme sport I’d never even heard of.  Castells in Catalonia go back to the end of the 18th century.  From the Castellers de Vilafranca:

Els Castellers de Vilafranca som una associació cultural que tenim com a objectiu aixecar castells.

 

Los Castellers de Vilafranca son una institución cultural y deportiva catalana que tiene como principal objetivo hacer castells (castillos, torres humanas).

 

Les Castellers de Vilafranca sont une institution culturelle et sportive catalane qui a comme principal objectif construire des castells (constructions humaines).

 

The Castellers de Vilafranca is a cultural and sporting association whose main objective is to build castells (human towers).

Note that the board is positioned incorrectly. The lower right hand corner should be a light square. You can also see a support bar between the table legs that suggests the correct orientation of the table. Of course, this isn’t about chess, it’s about art, but if you’re going to appropriate the game of chess as part of your art, get the chess right. I use real sudokus for my sudoku art.
