‘Lincolnshire?’ say friends who’ve never been there. ‘Flat as a pancake; just boring.’ More fool them. The westernmost corner of the county along the River Witham is wonderful for rambling, threaded by immaculately maintained and waymarked footpaths. There’s a subtle dip and roll to the landscape. Medieval sites, village with vigorous community lives; woods, ponds, moats, green lanes; west Lincolnshire has it all. Nonetheless, you rarely see another soul about the fields. What a pleasure it is to have such an undiscovered piece of walking country to oneself, especially on a drowsy afternoon after a pint and a sandwich in the flower-bedecked Royal Oak at Aubourn.

In a thistly field beyond the village, Jane and I found the Anglo-Saxon manor site of Hall Close, all lumps and bumps of grassed-over earthwork, half-dried moats and masonry. In a thicket by the river, broken fragments of wall and dragonfly-haunted pools showed where a monastic settlement once throve among its fishponds. Up the bank stood a 15^th-century dovecote of creamy oolitic stone with nesting holes for 500 birds - last remnant of Haddington Hall, seat of the ancient Meres family.

On the far side of a quiet green lane we went on across pastures heavy with meadowsweet, over pungent beanfields, through the slumbrous hamlet of Thurlby where mulberries and horse chestnuts half-smothered the houses. As we crossed the River Witham and came into Bassingham, the tower of St Michael & All Angels was striking three over a fantastic collection of gargoyles grinning and gurning from the church eaves. Did Walt Disney, on a visit to his ancestral village of Norton Disney a few miles away, come here taking notes? Certainly more than one of the Bassingham grotesques put us in mind of Mickey Mouse’s cock-eyed pup Pluto.

Bassingham was primping its herbaceous borders for Open Gardens Weekend. Schoolchildren queued up politely in Green’s Stores to buy sherbet lemons. Walking back along the well-kept field paths to Aubourn, watching swans on the river and listening to yellowhammers issuing their eternal requests for ‘A-little-bit-of-bread-and-no-cheese!’, Jane and I began to wonder if we had slipped through a crack in the space-time continuum and wandered into some improbable land of lost content.
