Following the restoration of historic properties. Dave Myers visits the Archbishop of Canterbury's London HQ, Lambeth Palace. He explores the incredible archive, discovers the human side of Britain's greatest kings and queens and has a look at Lambeth's 'loony left political heritage by admiring its street art. Dave helps to restore the Great Hall, which has hosted monarchs, archbishops and statesmen over the centuries. The current building was built in the 1660s after it was destroyed in the English Civil War and has one of the most impressive hammerbeam ceilings in the country. Dave and the builders can't wait to bring it back to life. Dave then indulges in some Thames-side time travel courtesy of local mudlarkers and prepares for a special topping out ceremony.
