2 Days in London: The Perfect London Itinerary
"What better place to start your London itinerary than with a visit to the Tower of London, home to the English Crown Jewels and the site of numerous key historical events, including the execution of all sorts of people who were deemed inappropriate by whoever was in charge at the time. These days there’s less blood running on the grass, but you will still find plenty to do, from popping in to see the monarch’s crown through to exploring the White Castle at the centre of the keep. My advice for getting the most out of your visit is to arrive as soon as the Tower opens, which is around 9am, and beating the crowds to the crown jewels. You’re likely going to want to spend at least an hour here, if not two – there is a lot to see (and photograph!) here."
