The Richard III Museum offers an entertaining and informative look at the Richard III controversy. Its major exhibition is a reconstructed trial where King Richard is placed in the dock and charged with the murder of his nephews, The Princes in the Tower. Following cross-examination from both Prosecution and Defence, the Judge sums up and the Jury (the visitors to the museum) are able to give their own verdict.
The uppermost room contains the newly-added execution chamber, where visitors are invited (quite literally!) to relive the executions ordered by Richard III in 1483.
Also within Monk Bar is arguably the World's smallest prison cell, which held recusant Catholic Alice Bowman at the time of Elizabeth I.
