A col is the lowest point on the saddle between two mountains. Graham Robb has spent years uncovering & cataloguing the 2, 002 cols & 105 passes scattered across the British Isles. Some of these obscure & magical sites are virgin cols that have never been crossed. Dozens were lost by the Ordnance Survey & are recorded only in ballads or monastic charters. The eleven cols of Hadrian`s Wall are practically unknown & have never been properly identified. These underappreciated slices of natural beauty provide a new way of looking at British history, & a challenge for cyclists & walkers.
