Telford town centre lies about east/south-east of Shrewsbury and north-west of Wolverhampton. The town comprises 7,803 hectares (30.13 square miles) and its southern and eastern parts, between the Severn Gorge and Donnington Wood, include the East Shropshire coalfield. North and north-west Telford lie beyond the coalfield's boundary fault on sandstone beds which, along with other Triassic formations, prevail over much of the North Shropshire plain. The town centre stands on a watershed, with land to the south draining towards the River Severn, and to the north the land slopes gently down towards the Weald Moors. The town is dominated by the Wrekin, a large hill of 407 m (1335 ft), located south-west of Wellington, straddling the border with the unitary Shropshire Council (before the latter's creation in 2009 the borough of Shrewsbury and Atcham).
