Max HeyraudDublin-based collectives ATEM and SOUNDMATE are set to return to Orlagh House on June 6th for the second edition of Untitled Castle, a day-to-night festival featuring Truly Madly, Lamache, Cáit, Holly Lester, Viki Dos Santos and more.
This year’s event embraces an Olympic-inspired sports theme, with guests encouraged to wear sportswear and take part in a range of sports activities and entertainment throughout the day.
Taking place across the grounds of Orlagh House in South Dublin, the event will feature three music stages alongside dedicated chill-out spaces, with programming running from 1PM until 3AM. The festival begins outdoors before moving inside the castle for its late-night closing chapter.
The 2026 edition welcomes two artists making their Irish debuts. UK artist Truly Madly and French producer Lamache will headline a programme that also places a strong emphasis on homegrown talent. Local artists Holly Lester, Cáit, Viki Dos Santos, Juslinis, Slim, Bernie & Vandi, Cam & Coco and Lapen & Kass complete the lineup.
Untitled Castle has aimed to create an experience that extends beyond the conventional festival format. Developed through a collaboration between ATEM and SOUNDMATE, the project centres around community-building, immersive environments and underground electronic music culture.
