The North and Central parts of the County are dominated by the Pennine Hills. Englands oldest National Park, the Peak District lies mainly within this county, and is an area of outstanding natural beauty. Peak District Towns include, Matlock, Buxton, Ashbourne and Bakewell (though Buxton and Ashbourne are just outside the Peak District Authority boundary). The east of the County is more industrial and it is here that the county's second largest town Chesterfield is located (with its famous crooked spire). The county town of Derby is in the south of the county. Other main towns include Ilkeston, Heanor and Swadlincote.
