With a population of 31,000, Wisbech is a small market town in the Cambridgeshire borough. The town has a civil parish and an inland port, used for trading purposes. The River Nene runs through the town and is separated by two bridges. Regardless of its size, since 2011, Wisbech has become the largest town in Cambridgeshire.
Wisbech is home to its own castle, which was originally built by William I to fortify the town. When the Tudors reined the area, they made it in to a notorious prison. It was used to capture political prisoners among Catholic priests. Many of the inhabitants were rumoured to have died due to insanitary living conditions. John Feckenham, the last Abbot of Westminster and Gunpowder Plot participants Robert Catesby and Francis Tresham were all kept prisoner here. The castle was rebuilt twice, once in the mid 17th century and then again in 1806 by Joseph Medworth. Remains can still be visited today.
