Editing Lancaster Castle (section)

===Refurbishment===
A large-scale refurbishment of the castle has been underway since 2011. In 2016 [[Historic England]] commissioned a tree-ring analysis of oak and pine timbers in the Keep and Gatehouse. The oak timbers in the Keep's undercroft were shown to have been felled in AD 1380s, whilst those from the Great Hall were probably felled slightly later, towards the end of the fourteenth century or very early-fifteenth century. The oak timbers in the Gatehouse were probably felled in, or around, AD 1404.<ref>{{Cite web|title=Lancaster Castle, Castle Park, Lancaster: Tree-ring Analysis of Oak and Pine Timbers in the Keep and Gatehouse.
