Littlehampton has a beautiful natural harbour at the mouth of the River Arun. The harbour provides a safe haven for all leisure craft as well as being a small commercial port.
The River Arun drains over 376 square miles of land, nearly all of which is in the county of West Sussex, through its entrance at Littlehampton. This is believed to be the largest catchment area of any river between the Medway and the Tamar along the south coast. If one imagines a bath as the catchment area and the plug hole as the mouth of the river, then it is a remarkably big bath and a remarkably small plug hole - just 30 metres or 100 feet in width at the entrance. The river also has the reputation for being the second fastest flowing in the country.
Littlehampton has been a port since Roman Times, but it only overtook Arundel as the river’s main harbour in the 1820’s. Maritime trade was the most important driver of Littlehampton’s economy until the railway first steamed into town in 1863. The new railway changed the face of the industrial areas of the town and brought holiday makers into the area - beginning the town’s booming leisure industry. Littlehampton had already officially been a town for a decade by this point and the motto - "Progress" (which still stands as the town’s motto) - must have seemed exceedingly appropriate.
