Gloriette, Schönbrunn Palace, Vienna.

“The garden axis points towards a 60-metre-high (200 ft) hill, which since 1775 has been crowned by the Gloriette structure. Maria Theresa decided the Gloriette should be designed to glorify Habsburg power and the Just War (a war that would be carried out of ‘necessity’ and lead to peace), and thereby ordered the builders to recycle ‘otherwise useless stone’ which was left from the near-demolition of Schloss Neugebäude.”
