Neunkirchner Allee#
Neunkirchner Allee Road, straight-lined road in the southern Steinfeld area between Wiener Neustadt and Neunkirchen. It was this even surface that P. J. Liessgang began the first basic survey of Austria in the years 1762-1770. In the south of Wiener Neustadt (in front of the former Neukirchner Tor gate) a Baroque stone column with an inscription topped by a globe commemorates this survey.
