You Missed a Spot (and Made a Mural)

Powerwashing has transformed Poland’s Solina Dam into a work of art.

Poland’s Solina dam, completed in 1969 and the tallest dam in Poland, has been collecting dirt and grime on its walls for decades. But when it came time for the 269-foot dam to get a good powerwash, the energy company Polska Grupa Energetyczna had an idea.

PGE worked with emerging comic book artist Przemek “Trust” Truściński to design a giant eco-mural honoring the wild and plant life found in the Bieszczady Mountains in southeast Poland, where the dam is located. At almost 300 feet wide and 177 feet tall, the mural is painted with a technique called “reverse graffiti.”
