Torksey Castle was a country house built in 1560 by Sir Robert Jermyn. It was destroyed during the English Civil War in 1645. Today, only the west facade and part of the rear wall remain.
Though the Jermyn family retained control of the estate after the Civil War, the property was not restored, but continued to deteriorate. The remains of the buildings were scavenged for usable building supplies by residents of the area. Also, the hall was built quite close to the flood-prone River Trent, which may have stood the family in good stead as a source of transportation and commerce (as the Lords of Torksey had been permitted to levy tolls on the river's travellers), but which also contributed to the damage of the building through flooding. In 1961, the Trent River Board buried part of the ruins when raising the river bank.
