Howley Park sandstone is from the Coal Measures of Carboniferous age.
It is a fine-grained stone, grey- buff to light brown in colour but
it tends to darken to a richer colour as it ages. This varied stone
is eminently suitable for a range of projects requiring walling material.
The stone is quarried from Howley Park Quarry south of Leeds in West
Yorkshire.
