The River Arun in West Sussex is crossed by several ancient bridges, including Greatham Bridge near Coldwaltham, which was originally built in the 13th Century, rebuilt in the 18th, adapted with a new span in the 19th and restored in the 21st.
In the 17th Century it was the scene of a minor battle during the English Civil War: the Parliamentarians seeking to wrest control of the strategic river crossing from the local Royalists. The graves of the dead from this skirmish can be found in the local churchyard.
The river itself was navigable in the 11th Century and by the 19th it connected to the Wey & Arun Canal, providing a link to London. As with all the inland waterways; demand fell away with the coming of the railways and maintenance of the navigation ceased in the 1890s.
The common along the western shore of the river is known as Waltham Brooks and is owned by Sussex Wildlife Trust. The line of the old navigation which here straightened a bend in the river can still be seen and still contains water. The remains of Coldwaltham Lock with its attendant keeper’s cottage are also present.
