Characteristics
White Siena is a predominantly white to light-grey granite characterised by the presence of darker crystals in elongated and irregular shapes. Quarried in the Viseu region, in north-central Portugal, it is distinguished by its dynamic appearance. Although the stone naturally presents a compact and aligned grain structure, the orientation of the cut creates a subtle sense of movement, resulting in a flowing and distinctive pattern.
Applications
White Siena is a versatile granite suitable for a wide range of interior and exterior applications. It can be used for flooring, wall cladding, countertops, façades and other architectural elements, adapting easily to both contemporary and traditional projects.
