Sheffield Castle
The remains of Sheffield Castle, at the confluence of the rivers Don and Sheaf, mark the site where the earliest settlement at Sheffield was founded sometime in the second half of the 1st millennium AD.
The original castle - thought to be a wooden motte and bailey type dating from the early twelfth century - was destroyed along with much of the town in 1266 during the Second Barons' War. The remaining stone foundations date from a stone castle built in 1270 and demolished in 1648.
In 1516 the alternative residence of Sheffield Manor was erected in a park attached to the castle. From 1570 to 1584, Mary, Queen of Scots was incarcerated by Elizabeth I in this and Sheffield Castle.
