I have an interest in such things. I think it is very interesting to find a hidden memorial or plaque which commerorates some previously well known, but now long forgotten pioneer or notable.
This one is located in Windsor, and marks the birth place of Robert Keayne (1595-1656) - A member of the Honourable Artillery Company of London; a distinguished member of the Colony of Massachusetts Bay, Founder and first captain of the Ancient and Honorable Artillery Company of Massacusetts (The oldest military organisation in the USA - 1638).
"A wise and public spirited citizen, a liberal patron of education, a generous contributor to thefoundation of Harvard College Cambridge Massachusetts 1636"
The plaque was erected by the Ancient and Honorable Artillery Company of Massacusetts USA 1912.
There are many such things - well worth watching out for them!
I include this tip as Windsor is renowned for being one of the most expensive places in the country for buying a house.
The house in this picture, which is very close to the Castle, has a plaque on the wall, saying that someone had put aside £500 in his will to build this house. Today £500 probably wouldn't buy you the front door!
Whilst we were walking through the town, we looked in the windows of one of the more up-market Estate Agents (property vendors), and noticed a houe for sale that we were parked very close to.
See my Transportation tip for on getting to Windsor by Car to see this house, and to find out how much a house in Windsor costs today!
This is probably the most important college in the UK and where all the rich kids study including Prince William and Prince Harry.
This college Locations isn't very far from the Castle, its located just across the river from Windsor though most visitors go to visit the castle only
Eton college's former Students include 18 British Prime Ministers !!!
There are also guided tours at Eton just check before you go.
