While visiting London town, are you willing to pay $50 to see Beefeater guides, the Crown Jewels and the cell where the two little princes were murdered? Also, if you arrive during the busy time of day, you may have to wait in line for an hour or so to peek at those historic sights.

Of course, for senior tourists who are English history buffs, this thousand-year-old prison is usually on the list of must-see locations. Also, it’s right next to the River Thames and the Tower Bridge. Also, if you’re wandering the grounds at the right time of day, you’ll see the famed ravens (English crows) hanging around for a biscuit or two.
