The Huntsman by Septimus Dawson
This picture is called the Huntsman and is by Septimus Dawson who lived from 1851 to 1914 in the North East - Sunderland, West Hartlepool and Scarborough. It is uncertain whether the scene showing a clapper bridge is real or imaginary but if anyone recognises the scenery or the bridge, please send us an e-mail - firstname.lastname@example.org
Clapper or pack-horse bridges are quite uncommon in the UK, there being only about 40 recorded to date. These bridges served as a way across streams or rivers and were often on pack-horse routes. A clapper bridge is usually constructed of one or more slabs of stone either with one stone stretching from bank to bank on a narrow stream or several supported by piers of dry-stone construction. Of those still surviving some consist only of the uprights with some or all slabs missing.

They vary in length from 3 to 54 metres and the purpose was to carry foot passengers and pack-horses but were too narrow to take wheeled vehicles. Within Britain the surviving examples are concentrated in Devon and Cornwall, particularly around Dartmoor and also North and West Yorkshire. They are more common where large slabs of flat but resilient stone could be found locally.

Dating is difficult unless there is other documentary evidence but their origins are likely to be from the late mediaeval period through to the early 19th century. The Anglo-Saxon word 'cleaca' refers to stepping stones and clapper may derive from this and in Sussex clapper is the term for a plank particularly where used as a footway.

So, the clapper bridge at Castle-upon-Alun, passed on both the Wick and Ewenny walks is not only unusual in South Wales but scarce throughout the UK. The length of this bridge is 28 metres. The width of the bridge varies as it tapers as you cross away from the road. At its narrowest it is 1.2 metres and 1.9 at its widest. Whilst the depth of the water will change through the year, typically the height of the top of the bridge above the water is just under 1 metre and it is 1.6 metres from the bridge surface to the bottom of the stream.
Gap tapering downwards with dressed stone above
The stone used is a mix of rough slabs and dressed rectangular blocks, the largest slab being 1.13 by 1.5 metres. The gaps in the bridge for the stream to pass through vary between 0.6 to and 1.1 metres in width.

Small Clapper Bridge near Sullu
This shows a smaller Clapper Bridge on Cog Moors near Sully with a single span consisting of a slab of limestone. It is on a footpath at ST 15025/68714 and passed on this walk.
