It is located near the village of Hrobčice in the Teplice district. A red hiking trail leads to the top and in ancient history there was a hill fort here. It dates back to the Early and Late Bronze Age. It is thus an important archaeological site from the Knovíz culture (8th to 6th century BC). A pair of ramparts and the remains of a well are still preserved here. The mounds are up to two metres high in places.
The upper part is currently protected as the Hradišťanská louka Nature Reserve. It has been declared for the protection of the plant communities of the foothill meadow, in which it is possible to find a number of rare plant species such as the highest upolina, low snake mord, white moss, amethyst fescue, golden-headed lily, narrow-leaved spurge, various-leaved pea and others. Orchids, which were the leading motive for the former designation of the nature reserve, have been absent for many years. They have disappeared mainly due to inappropriate management of the site.
Hradišťany is not a typical peak of the Bohemian Central Highlands. The peak is formed by a pebble-shaped body on a nephelinite escarpment, from which a trachyte ridge emerges towards the northwest. The flat, gently sloping summit is flanked by steep slopes with frost scarps, scree and boulder flows. The slopes are covered with mixed forests of spruce, beech and maple.
