The Mathematical-Physical Salon houses a world-famous historical collection of timepieces and scientific instruments. Since its foundation in 1728 it has been located in the Dresden Zwinger. On 14 April 2013, following a six-year construction phase, the Mathematisch-Physikalischer Salon will open its doors – thus providing access to outer space, the universe of science and the world of chronometry. Terrestrial and celestial globes and fascinating optical, astronomic, and geodesic instruments dating back to the sixteenth century will be on view, along with historical instruments and automats. These objects will not only provide an overview of the development and application of early precision instruments, globes and clocks, but also – as artworks of the highest quality – reflect their princely origins.
