Meridian Monument

The Meridian Monument stands on the cliffs near Newhaven, marking the prime meridian line that divides east from west. It's a modest concrete marker - nothing flashy - but the location itself is what counts. You get proper views across the Channel and a real sense of standing at a geographical point that actually matters on a map. The monument sits right on the edge, so watch your footing if it's windy. Allow 20 minutes unless you're the type who likes to linger on clifftops. Historians and geography enthusiasts will appreciate it far more than young children, who'll likely lose interest once they've worked out what it marks. The walk there is pleasant enough, and on a clear day you can see right across towards France. It's free to visit, naturally, since it's just a marker on open ground. If you're camping at Three Ponds Holiday Park or Brighton Caravan and Motorhome Club Campsite, both within a few miles, it makes an easy morning detour before heading into Newhaven proper. Chalky Downs is slightly further but still accessible for a short drive. Honest assessment: it's not worth planning your whole Sussex trip around, but if you're already in the area and fancy a clifftop walk with a bit of geographical significance attached, you won't regret the stop. Go when the weather's decent - there's nothing to shelter under, and autumn gales can be fierce here.
