The models, which are part of a makeover of the park’s Miniland London display, include The Gherkin, City Hall, and The Cheesegrater.
The display, which took 10,800 hours to create, also features One Canada Square, which stands as the tallest model on display at 5.5 metres high.
The miniature skyline is made up of seven buildings.
Ramesh Ganeson, vice president at Legoland Windsor Resort, said: “Miniland London continues to wow our guests since it first opened almost 30 years ago.
“Our continued investment in the resort has meant the iconic buildings have been updated for a new generation.
“Our talented team of model makers have skilfully refreshed and maintained the intricate details of the London city skyline, which is set to be a towering success.
“We are so excited to see the final models of these architectural gems in time for the new theme park 2025 season opening.”
It also features 25 animated houseboat and boat models, as well as 174 vehicles, including buses, taxis, and trains, to replicate the hustle and bustle of the city.
Lego buffs with a keen eye will also be able to spot some new coloured bricks used for the first time, including reddish orange and vibrant yellows.
To mark the attraction’s makeover, the Legoland Windsor Resort is calling all young builders and Lego enthusiasts to take part in a nationwide competition to become its first Mayor of Miniland.
Their winning design will be brought to life as a Lego model to go on display during the school summer holidays.

Day tickets to the Legoland Windsor Resort start at £29 per person and must be pre-booked online at the Legoland website.
