Our Commitment to Your Journey
We focus on ‘the bridge’, the space between insight and lived experience.
We offer a carefully held space for exploration, insight, and integration, grounded in trauma-informed care and psychological safety.
This retreat is designed for those who feel drawn to explore themselves more deeply — with curiosity, care, and openness.
The emphasis is not only on the experience itself, but on meaningful integration into everyday life.
THE SANCTURY
The setting unfolds in a beautiful farmhouse, nestled in a magical natural location close to dunes and the sea, featuring a Finnish sauna.
Space, tranquillity, and character define this beautiful country house, a centuries-old dune farmhouse. Built on a natural spring, it offers an abundance of space, and views of the garden and forest. There’s also an intimate garden room and a reading room or library. The wellness area consists of a Finnish sauna, outdoor shower, bucket plunge pool, foot bath, and cooling room, and you can take a dip in the pond!
ZeeVELD is a modern, beautiful venue situated close to the dunes and the sea, nestled within the Natura 2000 area: “The North Holland Dune Reserve.” It’s within walking distance of the sea and beach, secluded yet only 30 km from Amsterdam. The natural surroundings invite you to enjoy extensive walks on the beach, in the dunes, or in the woods, as well as wonderful cycling routes.
Offering a balance of comfort, privacy, and natural surroundings, the space provides:
- Comfortable accommodation
- A quiet, contained environment
- Access to nature for grounding and integration
- Sauna and wellness space
