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.GeologyThe 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.
