Federal Observatory, Observatory in District 6, Zurich, Switzerland
The Federal Observatory is a distinctive building with a tall tower in central Zurich that houses optical instruments for astronomical observation. Inside the tower sits a Zeiss telescope designed for precise measurements of celestial objects and phenomena.
Gottfried Semper designed this facility in 1864, moving astronomical work from the Grossmünster church tower into a dedicated research building. This shift reflected Switzerland's growing commitment to systematic scientific inquiry during the 19th century.
The Federal Observatory holds Class A designation as a Swiss cultural property, marking its contribution to Switzerland's scientific development.
The building sits in a central location easily reached on foot, though viewing requires patience with urban conditions. City lights limit the visibility of faint objects, so visits work best on clear nights when the sky is darkest.
The Zeiss mirror weighs about twelve tons and was manufactured in the 19th century with precision tools to deliver exceptional viewing power. This instrument remains a testament to optical engineering of that era and continues to serve for sky studies today.
