The history of Lincoln begins at Brayford Pool, a natural harbour on the River Witham. There was an Iron-Age settlement here as early as 100BC, known as "Lindun", or "The place by the pool". When the Romans invaded England they recognised the strategic importance of the place and established a garrison. They renamed the city "Lindum", and later "Lindum Colonia", from which derives our modern name of "Lincoln". Lincoln Cathedral which you see in the background, boasts an impressive central tower, the tallest in the country after Salisbury at 81 metres (approximately 250 feet). But this lofty finger of stone pales before the memory of the original tower, which rose twice as high before toppling in a storm in 1547. I had a wonderful day touring the old streets and shops more to show later..
