One of Charles III's scientific institutions, the Observatory was completed after his death in 1790. Beautifully proportioned, it's Madrid's finest neo-classical building, designed by Juan de Villanueva. It still contains a working telescope, which can only be seen by prior request. One room is also open to the public, but only on Fridays while the building undergoes renovation.
