Group Excursion to Mödling
–
Last week, the Kriegegroup went on an excursion to the beautiful hilltops of Mödling in Lower Austria. After arriving at the central station, Charlotte led us to the Bergruine Mödling, followed by a steep ascent to the Husar Temple, where we took the image below. Finally we ended up at the excellent Heuriger called Pferschy-Seper…
