Urania is a public observatory that rises prominently in the centre of Zurich.  The observatory sits atop a 51 metre tower.  The building below contains a plaque indicating it was designed by Gustav Gull and built between 1905 and 1907.  The observatory contains an optical telescope designed by Carl Zeiss AG in Jena, Germany.  Apparently, the  telescope was dismantled in March 2006, and returned to Jena to be restored. On April 25, 2007, the telescope was hoisted back into place in the dome and on May 4, 2007, its second opening ceremony was celebrated.
