If you enjoy visiting the many heritage sites around the UK and you are in the vicinity of Yorkshire, Brodsworth Hall is a must, and a full circuit of the gardens should not be overlooked, the above picture is of the Grotto, which is fashioned within what was the quarry which provided stone for the hall. The south facing rockery is thought to be the most extensive fern garden in the world, with examples from all regions of the planet. The fact it is sunk below the general ground level affords it a micro climate some latitudes south of the rest of the garden!
