These are incredible.
Included here among various alternatives for Tower Bridge, the Washington Monument, The Chrysler building and St. Paul’s Cathedral are proposed extensions to the White House, a 5 million tomb alternative to London’s famous Victorian cemeteries and a particularly uninspiring second place entry for the Sydney Opera House competition. My personal favorite, however is the Triumphal Elephant which could have capped off the Champs Elysees in Paris. If someone could only find the rejected competition entry for what became the Eiffel Tower, which consisted of a giant replica of a Guillotine.
Some I wish existed, some I’m glad didn’t become reality, and some I would like to see and then never see again.
