From Water Supply to Luxury Stay: The 100-Year Journey of Watertower Duin & Bosch
Looking for a romantic getaway that blends heritage, design, and breathtaking views? At the heart of the dunes in Castricum, Watertower Duin & Bosch transforms a more than 100-year-old national monument into a luxurious, private design hotel with a single suite and a 360° panoramic view. In this guide, you'll discover how a working water tower from 1908 became a one-of-a-kind stay 33 meters above the treetops — and what awaits you inside today.
Where it began: water for care and community
Watertower Duin & Bosch stands on the historic grounds of Duin & Bosch. In 1903, the state purchased 80 acres of dune reserve from Princess zu Wied, granddaughter of King Willem I. A year later, in 1904, a hospital was built here by commission of the Provincial Council of North Holland. To support the facility, the site included its own drinking water works — and the water tower you can now sleep in.
Completed in 1908, the tower stored treated dune water. Water was pumped from deep pits, filtered, and de-ironized before being held in a basin and then lifted into the tower. As with classic water towers everywhere, the elevated reservoir helped stabilize pressure and ensure reliable supply across the grounds.
By the end of the seventies, the buildings connected to the regional water network, and the tower’s original function ceased. For years it stood as a quiet landmark — until new plans brought it back to life.
A national monument transformed
Years later, restoration plans reimagined the abandoned tower as a unique boutique hotel with one room and panoramic view. The conversion placed the luxurious hotel suite within the tower’s original water reserve. To bring in more daylight, the entire roof was lifted and windows were added, honoring the monument while opening it to the sky.
Inside, you’ll notice a dialogue between steel and concrete that celebrates the building’s industrial past. Sustainable materials and high‑quality design products give the suite a modern, refined atmosphere. A striking architectural highlight — the “floating loft” — elevates the sleeping area and frames the 360° horizon.

A luxurious private suite at 33 meters high
The suite is an intimate, high‑end design space of about 20 m², created for quiet comfort. You sleep upstairs on the floating loft in a king‑size, round bed. All around, windows reveal a constantly changing panorama from 33 meters above ground: the coastline of Castricum to the west, farmlands to the east, and the treetops of the Noordhollands Duinreservaat to the north and south. As evening falls, distant city lights flicker; at dawn, birdsong greets the day.
