Overseal
Overseal is a village and civil parish in South Derbyshire situated 3 miles south of Swadlincote and 4.5 miles west of Ashby-de-la-Zouch. The population of the civil parish at the 2011 census was 2,450. It is one of the southernmost settlements in Derbyshire (after Netherseal and Lullington), situated close to the border with Leicestershire and lying within the National Forest area.
Historically both Overseal and Netherseal were part of Leicestershire: they were transferred from Leicestershire to Derbyshire in 1897, in return for Leicestershire absorbing several of Derbyshire's enclaves. ( See County Enclaves).
