Castle Hill is a scheduled ancient monument in Almondbury overlooking Huddersfield in the Metropolitan Borough of Kirklees, West Yorkshire, England. The hilltop has been settled for at least 4,000 years. The scheduled monument comprises the remains of a late-Bronze Age or early Iron Age univallate hillfort with a single raised bank, a later Iron Age multivallate hillfort, a 12th-century motte-and-bailey castle, and the site of a deserted medieval village. The grade II listed Victoria Tower on the summit of Castle Hill is by far the most conspicuous landmark in Huddersfield. The hill has been a place of recreation for hundreds of years and the easily discernible remains of past occupation have made it a subject for legend, speculation and scientific study. It is located on UK Maps at . Geology The hill owes its shape to an outlying cap of hard Grenoside sandstone that has protected the softer stone beneath from erosion. The slopes below Castle Hill are formed from alternating deposits of shale and harder sandstones and form a series of slopes and benches. Five coal seams lie within the shales of the lower slopes some of which have been worked along the hillside, by adits and shafts. Workings are visible in several places and there is also evidence of old quarries that have been infilled. History Early history The first people to visit Castle Hill were probably hunters and gatherers of the Mesolithic age, camping amongst the forests which at that time covered the land. In the Neolithic and Bronze Age, there appears to have been widespread travel or trade along the river valleys connecting the Yorkshire Wolds, the Peak District and the Mersey and Ribble estuaries. This is shown by various characteristic types of stone and bronze tools in a place far from their points of origin. The hillfort was constructed in the early Iron Age, around 555 BC taking up the whole hilltop. Modifications were made around 43 AD to improve the defences, probably in response to the threat from the Roman invaders. Excavations on part of the hillfort in 1970 demonstrated that Castle Hill had at some stage suffered from a severe episode of burning. Vitrified forts such as Castle Hill are rarely found in England, and are more usual in Scotland. The banks and ditches that remain are more likely to be the result of recutting and other alterations carried out during the Middle
