History

Built between 1774 and 1781 by the self-taught astronomer, Jan Hudde Eisinga (1743–1819), the planetarium is one of the oldest and most significant mechanical planetariums in the world. Eisinga created this intricate model as a means to predict comet passages and eclipses.

Architecture

The planetarium is housed within a modest, white-painted building that was originally designed to serve as a barn for cattle. The interior is dominated by the magnificent 18.5 x 6.5 meters (60 x 21 feet) celestial map, which features over 2,400 wooden balls representing planets, stars, and other celestial bodies.

Celestial Map

The celestial map is divided into two halves: the northern hemisphere on the left side and the southern hemisphere on the right. Each wooden ball represents a celestial body and rotates according to its orbital period, providing an accurate representation of the night sky at any given time.
