The pond, dug out in a crater-like, ovoid form and topped with a round wooden walkway and magenta-coloured Stalattite sculpture by Jacopo Foggini, is styled on runic exercise “funnels” that were dug into the ground for gymnastics practice and entailed considerable earth movement. A three-legged copper funnel with a bell-shaped and spirally swirling waterflow brings vitality to the biotope.
