If you’re planning a trip to London and were looking forward to seeing Big Ben, you might want to adjust your plans. You can still see the famous clock tower, but you’ll have to use your imagination since it’s mostly hidden behind layers of scaffolding — and will be, until 2021. Even the hand on the clock have been removed, and the bell is not chiming right now. As one of London’s most recognizable and photo-worthy landmarks, the obscuring of Big Ben has disappointed many tourists who weren’t aware of the construction, prompting several visitors to take their frustration to TripAdvisor. Unsurprisingly, people aren’t too happy that their photos are being spoiled by the necessary restoration and maintenance of a historic landmark.
