Bath Side Napoleonic Coastal Battery

Crumbling brick walls and grassy mounds mark where soldiers once scanned the North Sea for French invasion ships. Bath Side Napoleonic Coastal Battery sits on the Essex coast near Felixstowe, a proper piece of early 19th-century military engineering that's been left to the elements.

Built around 1810 when Napoleon's threat felt very real indeed, this coastal fortification protected the approaches to Harwich harbour. The battery's earthwork defences and gun positions are still clearly visible, though nature has softened the harsh military lines. History enthusiasts will appreciate the strategic positioning - you can see exactly why they chose this spot.

Families staying at nearby Suffolk Sands or Felixstowe Beach holiday parks might find the 20-minute walk from the seafront well worth it, especially if the kids are into castles and cannons. The site's completely open access, so you can explore at your own pace without queues or ticket booths.

Don't expect guided tours or interpretation boards though - this is archaeology in the raw. Bring a good guidebook if you want the full story. The coastal path continues north towards Harwich, making it easy to combine with a longer walk. Just mind the cliff edges - they're not fenced and can be unstable after storms.
