Roman military roads have been identified converging on the Birmingham area from "Letocetum" (Wall, near Lichfield) in the north; from "Salinae" (Droitwich) in the south east; from "Alauna" (Alcester) in the south, and from "Pennocrucium" (Penkridge) in the north west. In many places the courses of these roads – including the points where they met – have been lost as they pass through the urban area, though a section of the route from Wall is well preserved as it passes through Sutton Park. Roads are also likely to have led via the known Roman settlements at Castle Bromwich and Grimstock Hill near Coleshill to "Manduessedum" (Mancetter), and to the fort at Greensforge near Kinver. The existence of straight road alignments coinciding with early parish boundaries suggests another Roman road may have passed through Birmingham from east to west through Ladywood, Highgate and Sparkbrook, along the line of Ladywood Road, Belgrave Road and parts of Warwick Road. The Roman routes from Wall and Alcester were together named Icknield Street during the later Medieval period, though the implication that they were viewed as a single route by the Romans may be misleading, and it is possible that the road from Droitwich was originally the more important of the two southern routes.
