Podpeč limestone: a heritage stone from Slovenia

Abstract

AbstractPodpeč Limestone is characterized by its dark grey or nearly black colour, contrasting with white fossil shells of the mollusc Lithiotis. This formation, which has been dated as Lower Jurassic, occurs in southern and southwestern Slovenia and is particularly conspicuous in areas SW of Ljubljana. The main quarry, which is not active, is located near the village of Podpeč near Ljubljana and has been recognized as a geological site of national importance; as such, it is officially protected as a natural monument. The utilization of Podpeč Limestone was first documented during the Roman period in Slovenia. At the end of the 5th century AD, with the decline of the Roman Empire, stone-cutting ceased at Podpeč for many centuries. Towards the end of the 19th century Podpeč Limestone became better-known. During the first half of the 20th century significant stonecutting workshops were established in Podpeč with most stone being supplied from the main quarry. The internationally renowned Slovenian architect Jože Plečnik (1872–1957) used Podpeč Limestone in various Slovenian buildings, some of national importance. The utilization and national recognition of Podpeč Limestone within Slovenia provide abundant support for its nomination as a Global Heritage Stone Resource.
