Kass-Haff has announced its 2026 Open Day will be taking place on Sunday 10 May 2026 at its farm in Rollingen (87A rue de Luxembourg) between 10:00 and 18:00.
The annual festival is described as "a friendly, festive and socially engaged day” and will feature a ‘Bio-Second-Hand’ market, concerts and artistic events, community booths, play areas, crafts and shows for children, encounters with farm animals, as well as an organic restaurant offering on site.
The 2025 edition attracted nearly 2,000 visitors; this year again, the organisers are expecting a large and diverse audience from casual visitors to regulars (re-)discovering the vibrant and inspiring world of Kass-Haff.
A unique place, combining farm, education and social connection, Kass-Haff is much more than a farm: it is a small ecosystem where agriculture, education, culture and ecology meet. Founded in 2013 based on an extended community model, the farm works to connect citizens — both young and old — with the living world through an educational, sensory and participatory approaches. Parents of four, co-founders Tom and Anja envisioned a place where children, teachers and families can freely reconnect with the land, animals and everyday activities.
The rich and multigenerational programme includes:
• The “Organic Second-Hand” market
• Concerts, performances and artistic entertainment
• Play and craft areas for children
• Community and awareness-raising stalls
• Opportunities to meet the farm animals
• Organic products to taste and take home
The event is organised with the support of the Frënn vum Kass-Haff non-profit organisation, which actively coordinates this annual event, and with the participation of numerous local partners, such as: BIOG, Naturata, Bio-Lëtzebuerg, Etika, Mokidi, GreenFox, Lilynatur, Waldorf School, Vitalschnuffen non-profit organisation, Niessen Catering, Sunnen-Hoffmann Cellars, Addi a Merci and many others.
Kass-Haff welcomes around 50,000 visitors each year, whether they come for a workshop, a walk, an event or simply to shop at the on-site organic store. This unique space functions as a rural third place, open to society, transitions and future generations.
Car parking and free shuttle buses will be available from the P&R CFL Lohr (Mersch) and Veräinsbau (Rollingen), due to the large number of expected visitors.
