The deep origins
The deep origins of the Piasentina stone: The geological origins of the Piasentina stone and its millennial history as a building material are deeply connected to a unique geographical area in Europe: the Julian prealps area, on the border between Italy and Slovenia. Here, towards the late Jurassic period (about 145 million years ago) the Northern Adriatic seabed rose, creating a very special geological area. With its unmistakable light grey colour, sometimes verging towards brown or reddish, or maybe just tinged with white, the Piasentina stone emerges and outcrops along the slopes of the Natisone Valleys, through forests, meadows and vineyards.
The quarries were first used by the Romans for the construction of the nearby Cividale, the ancient Forum Iulii founded by Julius Caesar in the 1st century BC. They were then used during the time of the Lombards in the 9th century and throughout the ages for countless purposes: from churches to palaces and villas, from farmhouses to road pavings. Unknown craftsmen and the most famous names in the history of architecture have used it, including the Renaissance genius Andrea Palladio and the Art Nouveau architect Raimondo D’Aronco, all the way to the architectural and design projects of the 21st century.
A gift from nature
A gift from nature: Beauty, strength, durability, workability. The Piasentina stone stands out among the other stones for its qualities. One of the characteristic features of this stone is its low water absorption, making it ideal for urban paving and architectural covers. It allows you to create different finishes and surface textures using ancient traditional techniques and tools, adding unique value to each and every project where it is used.
Depending on how it is worked, the Piasentina stone responds with different tactile and chromatic effects, creating endless combinations from one single material. Different thicknesses are also available, for all kinds of uses. The Piasentina stone is a material without equal, whose geographic origins and geological and technical attributes are guaranteed internationally with the CE mark by the Consortium of Producers of Piasentina Stone, of which Iaconcig has been a member since its foundation in 1965
