Outside view only for free plus a history book will get you some great pics. Many excellent photo spots around. Saw torchlight commemoration of WW1 free. Choose the spot on the path that gets you the Tower and Tower Bridge together. Looks beautiful night and day. Pay attention to the traffic crossings so you stay alive >look left, <look right painted on floor to help . Live transport artery of a major city so take care and use underpass. Not a museum outdoors, you pay to go in for that to see the Crown Jewels etc.
