Old Observatory, Observatory in Leiden, Netherlands.
The observatory building contains original telescopes, multiple domes, and a visitor center within its historical walls adjacent to the botanical garden.
Built in 1860 to replace the original 1633 university observatory, this facility served astronomers until their relocation to new premises in 1974.
The observatory maintains its educational role through guided tours, astronomy events, and art exhibitions focused on scientific themes.
The facility welcomes visitors from Wednesday to Sunday, offering access to historical instruments and educational programs about space observation.
The observatory houses Einstein's Chair from 1861, named after the physicist who frequently visited during his time at Leiden University.
