This will be the most international edition of Stone Art, a biennial festival set in the rural quarry cluster near the village of Codaçal, Serro Ventoso parish, within the Serras de Aire e Candeeiros Natural Park.

“This is the edition in which we’ll host the largest group of international artists,” said curator Marco Almeida, known artistically as 2CarryOn. Alongside Portuguese participants, the line-up includes sculptors from Argentina, Saudi Arabia and Italy, and a muralist from Spain.

The programme will see the creation of seven murals, five sculptures and a collaborative graffiti piece by 11 writers. By the end of this third edition, Condaçal will boast around 50 public artworks, gradually forming an expanding art park.

The festival site comprises 13 active quarries, with ambitions to extend further into the mountain and integrate more of the extractive landscape. As in previous years, Stone Art will blend painting and sculpture, staying true to its mission of merging public art with rural settings and celebrating the region’s stone-extraction heritage and natural beauty.

Visitors can follow the artists’ progress from 23 August, with a guided tour on the 31st to present and contextualise the works.

This year’s muralists include Hatory Pabllo, Dish, Mafalda MG, Sea162, Fesa, Mojojojo and Jack Lack; sculptors Thierry Ferreira, Alfredo Pecile, Pablo Garelli, Kanu and Talal Altukhaes; and graffiti artists Crack, Hione, ISMO, Restless, Klit, Johnny Double C, Le Funky, Molin, Send, Trauma21 and Trip.

Highlights include two large-scale murals up to 40 metres long. Spanish artist Sea162 wiçç works using pigments made from local materials, painting while suspended in mid-air – a blend of climbing and art that aligns with the festival’s environmental ethos.
