The Normans planned the new town around the older one during the reign of Henry I.
The wide main street was designed for its market, and the narrow burgage plots running at right angles to it are typical of Norman architecture and planning, though today only Guildhall and Smallwood Lodge are clear signs of Norman buildings, due to the 1665 fire which destroyed most of the High Street.
The many half-timbered buildings surviving from the late medieval and Tudor periods confirm Newport's success, leading to the first market charter which was granted by Henry I.
The town is mentioned once by John Leland in a list of castles, though now no visible remains of the castle exist; however, the most probable location for it would have been the traditional site of a manor house at Upper Bar, where there is a fragment of a square, broad moat, or on the higher ground along the Forton road, where the Castle House school stands.
Like many rural market towns, Newport was influenced by industry; it served the needs of the mining area to the east of Shropshire and was also affected by mass-produced industrial goods that replaced traditional crafts.
Newport is located in the historic kingdom of Mercia, near where Wreocensæte, capital the Wrekin, was once situated.
The few fields that remained were for hay or cattle, forming a small green belt.
These estates exerted a powerful influence on the town, something obvious in the deference shown and respect paid to these landed families until at least the First World War.The burgesses received certain privileges from Henry I; Henry II, in an undated charter, granted them all the liberties, rights and customs that they had enjoyed in the time of Henry I, including a guild merchant, which is mentioned in the quo warranto rolls as one of the privileges claimed by the burgesses.Confirmation charters were granted by Edward I in 1287 and Edward II in 1311, while the town was incorporated in 1551 by Edward VI, whose charter was confirmed by James I in 1604.Medieval Newport flourished with trade in leather, wool and fish.Novoportans possessed the right to provide fish for the Royal table.The Normans planned a new town called Novus Burgus between the older settlements of Edgmond and Plesc, near the Old Quarry and Mere Park garden centre.
