In which European city did Arnold Bürkli work as a municipal engineer on a wide variety of construction projects?

Arnold Bürkli (February 2, 1833 – May 6, 1894) is principally known as a municipal engineer in Zürich, Switzerland.

Arnold Bürkli was also a railway engineer and, between 1855 and 1858, studied architecture in Berlin. Between 1860 and 1882, Bürkli worked as a municipal engineer on a wide variety of construction projects. After 1867, he completely reorganised and improved the city's water supply and sewerage system, subsequently becoming known internationally as a water supply expert.

'Bürkliplatz' in Zürich was named after him, as Arnold Bürkli was the leading engineer in the construction of the 'Quaianlagen' on the 'Zürichsee' shore, as well as of the 'Quaibrücke' bridge in Zürich.

The so-called 'Bürkliterrasse' opposite the 'Bürkliplatz' is also named after Arnold Bürkli. A sculpture honouring the tireless creating engineer being the driving force behind the new quays stands at the foot of the lake shore hill that elevates around 3 metres (10 ft) at the Arboretum Zürich. A simple monument was inaugurated in 1899, five years after his death, at Bürkli's favourite place in the Arboretum, or, in the words of the sculptor Richard Kissling, in the midst of his creation.
