The high-profile artist duo Allora and Calzadilla, who represented the US at the 2011 Venice Biennale, will unveil later this month one of their most ambitious and audacious works off Puerto Rico’s southwest coast.

The pair have installed a work by Dan Flavin—Puerto Rican Light (to Jeanie Blake), 1965—deep inside a natural limestone cave located in a remote conservation area on the Caribbean island between the municipalities of Guayanilla and Peñuelas. Solar panels at the mouth of the cave will power Flavin’s work, which is made from pink, yellow and red fluorescent lightbulbs.
