This castle is the oldest castle in Europe that is still lived in. The Queen (Elizabeth II) calls this castle her home and Buckingham Palace in London her office. When we visited Windsor Castle, the Queen was in Edinburgh, so we weren't able to see her. The inside of this castle is filled with armories, great halls, galleries, bedrooms with amazingly high ceilings, and the Queen's state apartments. In one room was Queen Mary's dollhouse. Erin could've been in that room for hours, looking at all the miniature furniture, etc. There were even little hand-written books by famous authors (for example: Sir Arthur Conan Doyle wrote a short story especially for Queen Mary's dollhouse's library).
