The world’s most iconic landmarks attract millions with their unique, striking designs – yet many of these were originally planned to look completely different.
Mind-blowing new images provide a vision of what six legendary structures might have become if their initial designs hadn’t changed.
Had the technology of their time kept pace with the vision of their architects, popular sites like St. Paul’s Cathedral, the Statue of Liberty, and Sydney Harbour Bridge could have taken on entirely different forms.
And now, Astrak, a global heavy machinery parts supplier, has brought those abandoned original visions to life using digital reconstruction.
James Coughlan, CMO at Astrak, said: ‘These reconstructions invite travellers to experience familiar destinations through an entirely new lens, revealing the alternative skylines, architectural wonders and cultural landmarks that almost existed, if today’s engineering, machinery and materials had existed centuries earlier.
‘By bringing long?lost designs back to life, we wanted to shine a light on the ambition and imagination behind the world’s greatest landmarks and reminds us that every destination has a story travellers rarely get to see.’
From forgotten bridge concepts to vanished super-structures, these designs reveal a hidden version of the past, where architectural ambition knew no bounds…
St. Paul’s Cathedral, London
‹ Slide me ›
Sir Christopher Wren, one of Britain’s most celebrated architects, had a much more ambitious plan for St. Paul’s Cathedral in his early plans.
Featuring a larger dome, a towering drum and a soaring interior, the original design pushed beyond what engineering in the 17th century could support.
Construction began in 1675, but as work progressed, practical limits forced significant changes – walls were thickened, aisles narrowed and piers enlarged.
The finished cathedral reflects these compromises, while this reconstruction shows the grander vision that might have defined London’s skyline.
Sydney Harbour Bridge, Sydney

Before construction began in 1923, the Sydney Harbour Bridge faced years of uncertainty – in fact, it almost didn’t happen at all.
Early designs included a massive central tower and several sweeping approaches, but they were rejected because the technology to span the harbour didn’t yet exist.
J.J.C. Bradfield’s steel arch design finally made the project possible, linking the city, and creating what was then the world’s longest steel arch bridge.
St Peter’s Basilica, Rome

Construction of the current Basilica began in 1506, replacing an earlier church that had stood in the Italian capital for over 1,200 years.
The original fourth-century, wooden-roofed structure was vast but deteriorating, with walls that had shifted metres out of alignment over the years.
It was eventually demolished to make way for the Renaissance building seen today.
This digital reconstruction reveals how the earlier Basilica looked to visitors centuries ago.
Statue of Liberty, New York
‹ Slide me ›
Construction for the Statue of Liberty began in 1876, but the idea started elsewhere.
French sculpture Frédéric Auguste Bartholdi first designed a colossal figure intended to look over the Suez Canal called ‘Egypt Carrying the Light to Asia’.
When the plan fell through, the concept was adapted into Liberty Enlightening the World in New York Harbor.
While the setting and meaning changed, the iconic torch-bearing figure remained.
Liverpool Metropolitan Cathedral, Liverpool
‹ Slide me ›
In 1904, construction began on Liverpool Metropolitan Cathedral, intended to be one of the largest cathedrals in the world.
Edwin Lutyens’ design included a colossal structure nearly 530 feet long, with a vast dome even wider than St. Peter’s in Rome.
However, the project was halted by wartime restrictions and economic hardship after only the crypt was built – and it now has a diameter of just 195 feet.
The new pictures show how much bigger it would have been had the original designs gone through.
Tower Bridge, London, UK
‹ Slide me ›
Following decades of debate over how to cross the river Thames without blocking river traffic, construction for Tower Bridge began in 1886.
Early proposals included large steel arches between the towers, but these designs were rejected.
The final solution – a bascule and suspension hybrid – allowed ships to pass while maintaining a crossing.
Earlier plans reveal how different London’s skyline could have looked.
