Treasure Discovered is the annual art festival presented by Mango Art Festival. The event gathers artists from diverse backgrounds—from local Northern talents to those from other regions—who will collectively transform a secret, 30-rai (12-acre) expanse at De Siam Warehouse into a vibrant creative and design space. The grounds will be filled with hundreds of unique artworks and craft pieces, bringing color to century-old traditional wooden rice barns. This artistic showcase is set amidst the antique furniture and collectibles from De Siam Antique Chiang Mai, the largest antique collector, restorer, and dealer in Thailand. This spectacular venue is only open to the public once a year, making the festival an exclusive experience.
