The Old Bishop's Palace is an historic visitor attraction in the city of Lincoln, Lincolnshire.
 When it was first built, in the late 12th century, it was at the centre of the vast Diocese of Lincoln, which stretched from the Humber to the Thames.
 The Palace was one of the most impressive buildings of medieval England, reflecting the power and wealth of Lincoln’s bishops.
 It is situated on a spectacular hillside site, just below Lincoln cathedral, providing extensive views over the city.
 The site lies immediately to the south of the Roman wall which had become the medieval defensive wall of the "Bail", which enclosed both Lincoln Castle and Lincoln Cathedral.
 The palace was damaged during the Civil War and subsequently largely abandoned.
 During the period that followed the Bishop’s main residence was Buckden Palace in Huntingdonshire.
 In 1841, following the reduction in size of the Diocese of Lincoln, the Bishop moved to Riseholme, to the north of Lincoln.
 This proved inconvenient and Riseholme was sold.
 In 1886 an older building on the western side of the Palace enclosure was substantially rebuilt and enlarged in a Tudor revival style by the architect Ewan Christian.
 A further change occurred in 1888 when the architects Bodley and Garner rebuilt and converted the southern portion of the medieval Great Hall into a chapel for the Bishop.
The Second Battle of Lincoln occurred at Lincoln Castle on Saturday 20 May 1217, during the First Barons' War, between the forces of the future Louis VIII of France and those of King Henry III of England.

 Thomas, the Comte du Perche, commanding the French troops, was killed and Louis was expelled from his base in the southeast of England.
 The looting that took place afterwards is known as the "Lincoln Fair".
 The citizens of Lincoln were loyal to Louis so Henry's forces sacked the city.
