The Lincolnshire Wolds is a nationally important and cherished landscape, much of which was designated as an Area of Outstanding Natural Beauty in 1973 on account of its high scenic beauty. In 1949 it was decided that unspoilt areas of the countryside should be protected for future generations as Areas of Outstanding Natural Beauty (AONBs). In 2000 the importance of AONBs was re-emphasised, acknowledging that they, with the National Parks, form Britain's finest countryside.
The Lincolnshire Wolds lie in the north-eastern quarter of the county of Lincolnshire, mid-way between Lincoln and the coast, surrounded by the relatively flat fens, coastal marsh and the Lincoln Clay Vale. The AONB comprises an area of 558 km² (216 miles²), while the wider Lincolnshire Wolds Character/Natural Area incorporates the two neighbouring areas of the 'Spilsby Crescent' to the south and the remaining chalk uplands to the north.
