Almost any tourist traveling to the UK follows the standard pattern. The visit program, as usual, includes a postcard view of Big Ben, a photograph against the backdrop of Westminster Abbey, and a visit to 221 Baker Street, where, according to legend, Sherlock Holmes lived with Dr. Watson.
More advanced travelers take selfies on Tower Bridge. Forgetting the Tower itself. And only very sophisticated tourists get an incredible dose of adrenaline, going down with an individual excursion into this dungeon. Of course, there is a budget version of the passage of this attraction.
