The monument consists of the remains of five limekilns, in which lime is made by calcining limestone. The kilns stand to a height of 10m, with two having been installed originally and three added later, though they are all of similar construction. The walls are of dressed limestone and are battered inwards. The two south-western kilns have shallow buttresses. The third kiln is set into a recess from the front line of the bank, joined to it by curving walls. The fourth kiln is flush with the front, but the fifth is recessed similarly. The drawing arches are segmental, with domed backs, and each has three drawing holes. All but the most south-westerly pot is open. They are lined with firebrick except for their uppermost parts, and narrow towards their tops. The north-eastern kiln steps down slightly and has an intact parapet.

The monument is of national importance for its potential to enhance our knowledge of industrial manufacturing processes. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structure itself may be expected to contain archaeological information concerning chronology and building techniques. A lime kiln may be part of a larger cluster of monuments and their importance can further enhanced by their group value. The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
