The Duke and Duchess of Sussex held their private evening wedding reception at Frogmore House after their Windsor ceremony, and it is also where their gorgeous engagement photographs were taken.
News Royal Editor Chris Ship described its personal and historical significance to the royal couple.
Like many a couple before them, Prince Harry and his wife Meghan are moving to the suburbs ahead of the anticipated birth of their first child.
"The couple have lived at Nottingham Cottage since their engagement past year".

That home, Anmer Hall, is where they often stay during the holidays, and they have also vacationed there several times.More news: Spain threatens Brexit veto as May makes final push
