Thundersbarrow Hill

Thundersbarrow Hill is an Iron Age fortification on a chalk ridge near Shoreham-by-Sea with an oval earthwork enclosure and visible banks. The site extends across a wider landscape with additional field structures and residential features that have been identified through archaeological study.

The site dates from the 6th to 3rd century BC and reflects Iron Age settlement patterns in southern England. Later during the Roman period, rectangular houses were built here, showing that the location remained in use over many centuries.

The site takes its name from a Bronze Age burial mound called Thunders Barrow that sits within the fortification. This ancient monument remains a physical focal point that connects the place to its earliest inhabitants.

The site is located on open ground and is accessible on foot, with the earthworks clearly visible especially in low light. Visitors should expect uneven terrain and wear sturdy footwear for a comfortable visit.

The hill's name comes from a prehistoric burial mound that was repurposed in 1873 when a water pond was constructed on it for practical reasons. This blend of ancient and Victorian-era modifications makes the location noteworthy in local history.
