Lincolnshire is incredibly rich in medieval churches from Saxon times onwards, many of them still little known. Lincoln Cathedral is justly famous, and second only to Durham in the grandeur of its setting. The prosperous years from the Middle Ages though to the eighteenth century have left a splendid legacy in the great town churches of Boston and Louth, in the innumerable village churches of the south of the county, the delightful manor houses (such as Tennyson's Somersby) and the Georgian town houses and coaching inns of Boston and Grantham, of Lincoln and Louth, and above all of Stamford. Monuments to industry include the vast maltings at Sleaford, the soaring dock tower of Grimsby, and an abundance of windmills.
