Hartham Park Ground Stone

Hartham Park Ground Stone has a wonderful creamy warmth and its distinctive, classic honey hue can be seen across the city of Bath. Due to its versatility, it has been used by generations of masons to help shape cities and towns across the UK. The Hartham Park block currently being extracted today is the same seam that has been worked for over two centuries, offering an unrivalled aesthetic consistency.
