Ungerberg, Mountain summit in Neustadt, Germany

Ungerberg is a mountain summit in Saxony that rises 537 meters (1,762 feet) above sea level. From the top, visitors can see across the forested landscape of the Sächsische Schweiz-Osterzgebirge region.

Tourism interest began around 1800, when the Neustadt theologian Wilhelm Leberecht Götzinger (1758–1818) praised the summit's view. In 1846 the lord of the manor at Langburkersdorf had a covered wooden lookout tower built, with a small inn at its foot; it burned down in December 1848. In 1883 the Neustadt publisher Julius Mißbach bought the summit and initiated the 18-metre stone Prinz-Georg-Turm, inaugurated on 14 June 1885.

The summit restaurant, reopened in summer 2018 by a foundation that bought the area, follows a hospitality tradition begun when a small refreshment stand opened beside the 1846 wooden tower. The stone Prinz-Georg-Turm is named after Prince Georg of Saxony, who visited the summit on 1 October 1885; King Albert of Saxony came on 21 July 1887.

Six marked trails reach the summit: blue, red and green from Neustadt in Sachsen, yellow and green from Rugiswalde, yellow from Dolní Poustevna, blue and red from Sebnitz, yellow via Schönbach and green from Krumhermsdorf. A paved access road, built between 1934 and 1937 as a relief-work project, also leads to the top. In winter the descent toward Krumhermsdorf is used as a sledding run, and a ski lift stands in Rugiswalde.

The 74.9-metre FMT 9 telecommunications tower beside the summit was built after German reunification and broadcasts analogue FM and DAB+ radio; the viewing tower itself gained its roughly 33-metre height in a 1973 renovation.
