From touching Yorkshire and Cheshire across the Pennines it reaches far south to Warwickshire. Derbyshire has extraordinarily varied scenery: gritstone cliffs in the Peak at Kinderscout, limestone in Buxton and Dovedale, Trentside villages settled by Saxons and Vikings, leafy warrens through unposted lanes to medieval houses, churches and timbered halls. It has the best collection of stately homes from Chatsworth, Hardwick and Sudbury to fortified Haddon Hall and the magic of Bolsover's pretend 17th century castle - built by a Carolean courtier living like a knight of the Round Table. Here, in former mining country, are creamy limestone cottages with red pantiled roofs. Industrial archaeology can be be found here too in 18th century cotton mills, similar to many attracted to the Derwent Valley which is a World Heritage Site. Derby itself has clusters of silk mills and, nearby in the south east, daunting big lace mills. Here, at the foot of the county is Brindley's Grand Trunk Canal, also part of the Industrial Revolution, connecting the east-flowing Trent to the Mersey ports.
