The history of Castleton is inextricably linked to the Norman Conquest of England. Unlike many ancient settlements that grew up spontaneously, this town was created as a planned fortified outpost designed to establish the new authority in the Peak District region.
Foundation and First Mentions
The settlement owes its emergence and name (literally "town of the castle") to the construction of Peveril Castle. The fortress was established shortly after 1066 by William Peveril, who, legend has it, was an illegitimate son of William the Conqueror.
In the famous Domesday Book (1086), Castelli in Pechesers (Castle in the Peak's Arse) is mentioned; however, the settlement itself at the foot of the hill formed slightly later, in the 12th century, as a satellite town to serve the garrison and administrative needs.
Key Factors of Formation
The development of Castleton was determined by a unique combination of geographical and political conditions:
- Royal Forest: The town became the administrative center of the "Royal Forest of the Peak"—a vast area set aside for royal hunting.
- Strategic Defense: Its location in the Hope Valley, protected by steep hills and Mam Tor mountain, made it an ideal spot for controlling the northern territories of Derbyshire.
- Urban Planning: Castleton is a classic example of medieval urban planning. It was laid out on a regular street grid, traces of which are visible today, and a defensive ditch known as the Town Ditch was built around the settlement.
Early Economy and Resources
In addition to serving the castle, the prosperity of early Castleton was based on the extraction of natural riches hidden within the local hills:
- Lead Mining: Mines in the surrounding area had existed since Roman times, but in the Middle Ages, lead mining became a key industry, bringing significant income to the Crown and local lords.
- A Unique Mineral: It was here that deposits of the rare fluorite known as Blue John were discovered. This beautiful stone was used to create jewelry and bowls, eventually making the region famous far beyond the borders of England.
