Macchiavecchia Marble

Located in Ticino, Switzerland in the underground depths of a prehistoric seabed lies the Arzo quarry which extracts Macchiavecchia marble. A polychromatic calcareous marble. The geological movements that led to the formation of this rock caused it to fragment and crystallise with other minerals, giving it a very varied chromatic colour with exquisite bold-coloured veins of red to yellow to olive green and even white. Macchiavecchia marble is a versatile material that is ideally used for interior and exterior projects: such as wall veneers, flooring and/or for ornamental purposes.
The Church of Gesù Nuovo (New Jesus) in Naples is an iconic masterpiece of how this marble has been used over the centuries, creating extraordinary works of art.
