Every garden or outdoor space needs an attractive focal point or central feature to complement the surrounding environment. If you’re looking to add some intrigue to your garden, there’s nothing quite like a striking slate monolith.
Monoliths and standing stones have been used across the world for thousands of years for different purposes, such as decorative, religious, or imposing landscaping features.
Even the mysterious Stonehenge was originally built with smaller bluestone from Preseli Hills in southwest Wales. In fact, they loved the stones so much they moved them over 150 miles east to Wiltshire! These days, striking Welsh slate is used for monoliths, holloliths, standing stones and feature stones for gardens and are the perfect way to create a statement or an unusual talking point.
No matter what style of garden you have, slate monoliths look absolutely stunning and are a real conversation starter. They are larger and taller than decorative aggregates, and single slate stones may be either chunky or slender.
Slate standing stones do not come with flat bases and are designed to be dug into the ground to give a solid height and form. They are slightly shorter than beautiful slate monoliths, but they are equally captivating. Slate standing stones can be used either individually or in groups to create a design feature unique to your garden which complements planting areas, rockeries, gravel gardens or water features.
By contrast, feature stones are not as tall and vary in size; some are cut to create a clean look, and some are left to their natural shape. Feature stones and monoliths make an absolutely stunning centrepiece for any garden, gravelled area or rockery, and as they have flat bases they do not require burying into the ground.
