The Mathematical-Physical Salon houses a world-famous collection of historical clocks and scientific instruments. Since its foundation in 1728, the museum has been located in the Dresden Zwinger. The museum opens its doors - and with it the door to outer space, to the universe of science and to the world of clock art at the same time. On display are terrestrial and celestial globes as well as fascinating optical, astronomical and geodetic devices dating back to the 16th century, and historical instruments and automata. These not only provide an overview of the development and application of early precision mechanical instruments, globes and clocks, but also reflect their princely origins as works of art of the highest standard.
