Considering the Eardley's Hotel Lincoln in Lincoln?

Lincoln Castle by Cheersmates
Here it's where one of the last pieces of Magna Carta is kept. Magna Carta was the first ever constitution in the UK, in the 1200's and a number of different documents were written and distributed, but only a few remain today.
In the castle, you can visit the museum of the old prison and also walk on its walls which then you have the view of the whole of Lincon and surrounding areas. Great on a clear day.
Also in the summer it's a great place to go with babies/kids and they can play in the grass and run free.
