Grassi Pietre, thanks to its continued commitment to spreading the culture of art connected with Vicenza Stone, started a fruitful collaboration with The Landmark Trust, one of the UK non-profit organizations dedicated historical buildings preservation and restoration. Grassi Pietre therefore participated actively in the residential seminar offered by SPAB "Society for the Protection of Ancient Buildings". This institute was founded by William Morris in 1877 and is one of the most important for conservation and restoration in the UK . The company organized for three participants a guided tour in its headquarters , and an experiential journey through one of the owned quarries. These three young professionals have thus been able to see with their own eyes where we extract Vicenza Stone , founding elements for Andrea Palladio architecture , they saw how the stone is worked and what kind of magnificent architectural elements that can be produced .
