With its height of 1,178 metres (3,865 ft), Sveta Gera (Croatian: "Mount St. Gertrude") or Trdinov vrh (Slovene: "Trdina Peak") along the border between Slovenia and Croatia is the highest peak of the Žumberak/Gorjanci mountains.
The peak was originally called Sveta Gera in Croatian and Sveta Jera in Slovenian (Mount St. Gertrude) after the 15th-century church of Saint Gertrude some hundred meters from the highest point of the peak. In 1923, however, the president of the Novo Mesto Mountaineering Club Ferdinand Seidl proposed to rename it after Janez Trdina, an ardent describer of the region. On 15 August 1923, the peak was ceremonially renamed by a Slovene girl, while the accompanying ecclesiastic rituals were performed by a Croatian priest.
The summit is subject to a border dispute between Croatia and Slovenia.
