In Ukraine, there are several hundred natural geological monuments that, when destroyed, can not be restored and therefore require the most careful attitude. The geomorphological features of cities disappear due to the ever more anthropogenic load. Complicated relief is no longer an obstacle to construction due to the progress of construction technology. Outstanding features of the city's geomorphology can be preserved through the creation of complex programs for preserving monuments of different categories, which would be mutually supplemented and maintained with the help of protection zones. Detection and estimation of potential objects for initiation of security measures are based on historical and morphological analysis of elements of the city and the use of systematic, biomorphological, ecological, geographical analysis of cultivated dendroflora.
Lviv has a complex relief, due to which it was formed. Here we distinguish various geomorphological elements, which together make the Main European watershed. To the west the hills of Roztochia strand reaches, from the east - the ledge of Podillia plateau is observed. Several geomonuments of geomorphological origin are located within the limits of the almost million metropolitan area of Lviv: Mount High Castle (409.5 m above sea level), Lev Mount (389 m), Kortum Mount (372.5 m), limestone Chotovi Skeli (414 m) and Medova Pechera (Honey Cave).
In the modern structure of the city, the hills are part of the natural framework of the city's greenery system and make up its two wedges – the South-East and the North-West wedges. The most significant dominant point is High Castle Mount, which is part of a chain of planar erosion remnants and together with city center is a part of the UNESCO Conservation Zone. The top of the mountain is crocheted artificially from the walls of the medieval castle during the 1869-1900 with the cone-shaped hill in honor of the Union of Lublin, 36 m high. Over time, the hills were planted, and from the 19th century became the basis for the creation of landscape parks and walking alleys. Here the park "High Castle" with an area of 36.2 hectares is formed which is the main object of tourist excursions.
In modern Lviv planning, geological monuments are complemented with memorials of botanical, historical, garden and park art and forest parks. According
to the Law of Ukraine on Nature Conservation and National Parks "About the Nature Reserve Fund of Ukraine", which guarantees a balance between the territories designated for the protection of nature and development, the system of nature protection objects of Lviv has been developed.
