Our bus into town got stopped early, so we ended up walking the rest of the way and spotting lots of new things.
First we discovered New Scotland Yard with the spinning sign you see on the news.
There's an eternal flame burning outside the building for police who have lost their lives in service.
Around the corner we passed the very imposing looking Ministry Of Defence building with it's huge silver doors.
At Horse Guards Parade, I was wondering how I'd get a photo of the horses without any tourists in when one of the horses pushed a lady out of the way with his nose so I could get a clear shot.
