Tlmače – the city at the Slovenská brána (Slovak gate) Natural conditions
The city of Tlmače is mostly located on the left bank of the river Hron bottomland on the south-west foothill of the Štiavnica hills (Štiavnické vrchy). Newer part of the city – Lipník – was built on the right bank of the river Hron on elevated terrain sloping towards the river. The place, where Hron leaves the mountains, was called Porta Slovenica, i.e., the Slovak gate by our historians. This geo-morphological formation was modeled by erosion activities of the river Hron, which broke through settled volcanic agglomerates and separated the Kozmálovce tops (Kozmálovské vŕšky) from own Štiavnica hills.
