Titterstone Clee Hill, sometimes referred to as Titterstone Clee or Clee Hill, is a prominent hill in the rural English county of Shropshire, rising at the summit to above sea level. It is one of the Clee Hills, in the Shropshire Hills Area of Outstanding Natural Beauty. The nearest town to the hill is Ludlow, which can be seen from parts of Cleehill village. Geography Titterstone Clee is the third-highest hill in Shropshire, surpassed only by the nearby Brown Clee Hill () and Stiperstones (). Much of the higher part of the hill is common land, used for the grazing of sheep, air traffic control services and both working and disused quarries. The summit of Titterstone Clee is bleak, treeless and shaped by decades of quarrying. Many of the industrial structures still remain. Most of the summit of the hill is affected by man-made activity, the result of hill fort construction during the Bronze and Iron Ages and, more recently, by years of mining for coal and quarrying for dolerite, known locally as 'dhustone', for use in road-building. Many derelict quarry buildings scattered over the hill are of industrial archaeological interest as very early examples of the use of reinforced concrete. The village of Cleehill lies on this road as it crosses the hill. At above sea level, it was home to what was, until it closed, the highest pub in Shropshire, called The Kremlin, and also to the highest primary school. On the northeast slope of the hill is the small village of Cleeton St Mary. Geology The hill rises above the surrounding countryside by virtue of its distinctive geology, the igneous rocks capping both Titterstone Clee and Clee Hill being more resistant to erosion than the neighbouring sedimentary rocks. Most of the lower ground is underlain by mudstones and sandstones of Devonian age and collected together as the Old Red Sandstone. The uppermost part of this succession is the St Maughans Formation and on the northern and western sides it rises almost to the summit where it is then capped by a hard-wearing dolerite sill. A similar but larger and separate intrusion caps Clee Hill to the south. The Old Red Sandstone is unconformably overlain by Carboniferous Limestone which locally is accounted for by the Orton Limestone Formation and the Lower Limestone Shale Group. These rocks occur in a curved outcrop to the south of Cleehill village and
