The circular building with 28 windows corresponding to the lunar cycle on each of its 5 floors is the Narrenturm or Fools Tower. It is one of the lesser known landmarks of Vienna. It was built by the Austrian emperor Jospeh II in the 18th century.
In the centre of the circular building there was (until about 1910) a tower where his majesty had his own apartment and from which astronomical observations could be made and views over the rural landscape and the nearby city could be appreciated, for in the time of the emperor the Narrenturm was situated outside the city which has in modern times expanded to include it.
Other residents (apart from the emperor who refused to reside in the Schonbrunn Palace but preferred to travel incognito into every nook and cranny of his empire to talk to his subjects on more or less equal terms) were the emperor's collection of lunatics and the medical staff. The Fools Tower was a majestic hobby as well as being a royal escape hole; somewhere safely away from the pressures of being an emperor.
The Vienna public who enjoyed visiting the tower at the weekends and climbing up its walls to peer through the windows at the patients within had no idea that the face looking down on them from the topmost point, from the apartment at the summit of the tower, was no other than their emperor.
Because the primitive toilet system in the 18th century building was continually blocked with human and other waste the interior of the building was reputed to be the smelliest place in Vienna. One can imagine the effect of the foul stench on the weekend curiosity seekers peering through the glassless windows of the tower in the summer months and their reaction; perhaps the inhabitants, after the initial shock, were immune to the smell.
In winter the Narrenturm would be bitter cold. There were attempts involving steam and smoke to provide a kind of central heating for the Narrenturm but unfortunately they failed miserably.
