SM Stirling's Emberverse Vol II, The Protector's War (New York, 2006), begins at Woburn Abbey, England, in 2006 AD, Change Year Eight. An ex-SAS man thinks:
"I've been here before..." (p. 1)
So have I, although too long ago to remember anything.
"In 1953 the eleventh duke had opened [the Abbey] to the paying public, complete with golf course, pub, guided tours and antique shop - and avoided the forced sales which so many of his peers suffered after the Second World War." (p.2)
There is a lot of that in England. Also, former private residences are outdoor pursuits centers etc.
It is always interesting to read a North American author's account of a visit to a historic site in England. In particular, see York Minster.
