Eise Eisinga Planetarium

In the charming town of Franeker, nestled in the northern province of Friesland, the Eise Eisinga Planetarium stands as a testament to human curiosity and ingenuity. Known locally as the Koninklijk Eise Eisinga Planetarium, this remarkable establishment is not just a museum but a living, ticking marvel of astronomical engineering. Constructed between 1774 and 1781 by Eise Eisinga, a wool carder with a passion for astronomy, it holds the distinction of being the oldest working planetarium in the world.

The History of the Eise Eisinga Planetarium

The story of the Eise Eisinga Planetarium begins with a celestial event that sparked fear and intrigue in the hearts of the local populace. In 1774, a pamphlet by a local preacher predicted a catastrophic collision of planets that would hurl Earth into the Sun. To quell the ensuing panic, Eise Eisinga embarked on an ambitious project to build a scale model of the solar system on the ceiling of his living room. His goal was to demonstrate the predictable paths of the planets and dispel the myths of impending doom.

Eisinga's project, initially expected to take a mere six months, extended over seven years. He meticulously crafted a mechanical model powered by a pendulum clock, which accurately depicted the orbits of the known planets at the time: Mercury, Venus, Earth, Mars, Jupiter, and Saturn. The planets, represented by spheres painted in gold on the sun-facing side, revolve around a central sun, with Earth accompanied by its circling moon. Despite the discovery of Uranus in 1781, Eisinga's model remains a snapshot of the universe as it was known in his day.

Exploring the Planetarium

Visitors to the Eise Eisinga Planetarium are greeted by a quaint, gabled brick facade that belies the wonders within. Stepping inside, you're transported back to the 18th century, where the intricate mechanisms of the planetarium continue to operate as they have for centuries. The ceiling, a masterpiece of astronomical art, is painted a deep blue and adorned with zodiac signs and celestial markers.

The planetarium's clockwork, ingeniously hidden in the attic and above the bedstead, controls the movement of the planets with astonishing precision. This mechanical marvel not only displays the positions of the planets but also provides information about the phases of the moon, the times of sunrise and sunset, and the current date according to the Christian calendar.

A UNESCO World Heritage Site

In recognition of its historical and scientific significance, the Eise Eisinga Planetarium was added to the UNESCO World Heritage List in 2023. This prestigious designation highlights the planetarium's role as a rare example of scientific heritage and its enduring contribution to our understanding of the cosmos. It stands alongside other world-renowned sites, celebrated for its blend of scientific innovation and cultural history.

The Museum Experience

Beyond the planetarium itself, the museum offers a rich tapestry of exhibits and experiences. The expansion of the museum complex includes a former coffee roastery and a former pastry shop, now serving as the entrance and exhibition spaces. These areas host both permanent and rotating exhibits, providing insights into the life and times of Eise Eisinga, as well as the broader context of astronomical discovery.

A visit to the museum is not complete without a stop at the film room, where documentaries and presentations bring to life the story of Eisinga's visionary creation. For those seeking a moment of relaxation, the museum's café offers a cozy spot to reflect on the wonders of the universe over a cup of coffee.
