Mains water arrived in 1947 and mains electricity in 1948 .  - Shropshire (or ; alternatively Salop; abbreviated, in print only, Shrops; demonym Salopian ) is a county located between West Midlands in England and Wales. It borders Powys and Wrexham in Wales to the west and north-west, Cheshire to the north, Staffordshire to the east, Worcestershire to the south-east and Herefordshire to the south. Shropshire Council was created in 2009, a unitary authority taking over from the previous county council and five district councils. The borough of Telford and Wrekin has been a separate unitary authority since 1998 but continues to be included in the ceremonial county.  - In England, a civil parish is a territorial designation which is the lowest tier of local government below districts and counties, or their combined form, the unitary authority. It is an administrative parish, in contrast to an ecclesiastical parish.  - The name Rea Brook can refer to either of two brooks (a local term for a small river) in Shropshire, England.  - A County town is usually the location of administrative or judicial functions within the county, or it has been established over time as the "de facto" main town of a county. The concept of a county town eventually became detached from its original meaning of where the county administration or county hall is based. In fact, many county towns are no longer part of the administrative county. For example, Nottingham is administered by a unitary authority entirely separate from the rest of Nottinghamshire. Many county towns are classified as cities, but all are referred to as county towns regardless of whether city status is held or not.  - England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest.

It sits in the Rea Brook valley. To the south are the Stiperstones and the Bromlow Callow, known for the small clump of trees on top. To the north is Long Mountain.  - The Stiperstones is a distinctive hill in the county of Shropshire, England. It is a quartzite ridge formed some 480 million years ago. During the last Ice Age the summit stood out above the glaciers and was subject to constant freezing and thawing which shattered the quartzite into a mass of jumbled scree surrounding several residual rocky tors. At above sea level it is the second-highest hill in the county, surpassed only by Brown Clee Hill. Stiperstones' summit ridge is crowned by several rugged, jagged outcrops of rock silhouetted against the sky.
