Magna Carta is on display at the Ronald Reagan Presidential Library

One of four original copies of the Magna Carta is the centerpiece of a new exhibition at the Ronald Reagan Presidential Library and Museum in Simi Valley.

The exhibition ends June 20 and will include scenes from life in England in 1215, the year the Magna Carta was recorded. The document, considered important because it guaranteed basic freedoms and rights, is owned by the Lincoln Cathedral in Lincolnshire, England.

According to the cathedral’s website, the bishops of Lincoln were among the magnates of medieval England. When the Magna Carta was issued in 1215, one of the witnesses was Hugh of Wells, Bishop of Lincoln, who returned with his copy to the city. Today, Lincoln’s copy of the document is one of four originals from 1215 that still exist.
