The large mound in the centre of town is what remains of the 12th century fortifications, and within it is the 12th century hall still called 'Oakham Castle'.
Once called the Shire Hall, this building dates from 1190 and is in something like original condition, with round headed arches and dog-tooth carving. It was re-roofed in the 17th century and again in the 19th, although at least two original roof beams have been identified.
The hall, was built by Walchelin de Ferrers at the end of the 12th century. Its architectural details point to a period within the ten years between 1190 and 1200; Ferrers died in 1201.
The Hall has long been used as courtroom, a duty it still serves to this day. But its most famous feature are the "horseshoes" displayed around the walls, relics of a long tradition that any Peer of the Realm passing through the county has to pay a fee in the form of a horseshoe. (It is my personal view that this originated as a way of disabling unexpected military visitors)
The building is, unsurprisingly, a grade I listed structure
