In the Great Hall of Oakham Castle

Only the great hall of the Norman castle is still standing, and is surrounded by steep earthworks marking the inner bailey. The hall dates from c. 1180—90 and according to Nikolaus Pevsner (in his "The Buildings of England: Leicestershire and Rutland.
It is the earliest hall of any English castle surviving so completely, and it is doubly interesting in that it belonged not to a castle strictly speaking, but rather to a fortified manor house.
The building is attractively ornamented with Romanesque architectural details, including six carvings of musicians. It is a grade I listed building.

The hall was in use as an Assize court until 1970 and is still occasionally used as a Coroner's court or Crown Court. It is also licensed for weddings.

A Castle class corvette named HMS Oakham Castle was launched in July 1944.

The castle contains over 200 horseshoes, given as gifts to the Lord of the Manor; by peers of the realm, and Royalty, as they pass through Oakham.
