69. Mochovce Nuclear Power Plant

Location: Mochovce, Slovakia
Total Cost: $7.61 Billion*
Year Finished: 2023
Construction of the Mochovce Nuclear Power Plant began in 1983, and it was signed off and commissioned 15 years later. Over the years, extensive work has been done to maintain and improve the plant, but the work hasn’t been cheap — especially with the latest two additions to the plant.

The current work being done on the power plant involves the construction of the plant’s 3rd and 4th units. When all four are up and running — which they should be by 2023 — their net output will be approximately 1,842 Megawatts. That’s enough power to support close to 40 million households.

70. Nya Karolinska Hospital

Location: Stockholm, Sweden
Total Cost: $6.61 Billion*
Year Finished: 2018
In 2008, the Stockholm County Council came to a consensus that the university in Solna was in need of a new teaching hospital. Ten years and $6.61 billion later, a 12-floor 3.5 million-square-foot masterpiece had been built, and so far it looks like it was worth every penny.

By 2016, even though it wasn’t quite completed yet, the pediatric unit and cardiovascular themes had already begun to move into the New Karolinska University Hospital. The rest of the hospital was operational by the end of 2018. The private-public model of the Nya Karolinska Hospital was initially thought to be a pipe dream but has since proven to be a success.

71. Camp Nou

Location: Barcelona, Spain
Total Cost: $1.73 Billion*
Year Finished: 1957
After three years of construction and hundreds of millions of dollars, Camp Nou opened in 1957 and has been the home of the FC Barcelona soccer club ever since. Over the years, the stadium has been renovated three times – 1995, 2008, and most recently, 2018, each ensuring a longer life for the beloved building.

The initial build and all the renovations came to a total of $1.73 billion that has been poured into Camp Nou over the years. With all the stadium’s changes, one thing has remained the same — the spirit of the 99,354 fans who fill the stadium for every match.

72. Øresund Bridge

Location: Between Denmark and Sweden
Total Cost: $6.5 Billion*
Year Finished: 1999
A massive project plan was pitched in the 1930s, which was to connect Sweden to Denmark (via Malmö and Copenhagen). Following decades of delays, constant chatter as to whether or not it would work, and multiple cancellations (and renewals), the Øresund Bridge was finally completed in 1999.

It took $6.5 billion to finish the work, but when it was done, the Øresund Bridge was a sight to see — most of it anyway. The three-part system includes the Drogden Tunnel — which traverses around 2.5 miles underwater — the beautifully designed 4.87-mile bridge, and Peberholm — the artificial island that serves as the entry point for the Drogden Tunnel.

73. Universal Studios Beijing

Location: Beijing, China
Total Cost: $6.5 Billion*
Year Finished: 2021
Announced in 2014 but not completed until early 2021, Universal Studios Beijing was an undertaking like few others that came before it. The 130-acre, $6.5 billion project was aimed at creating movie worlds for its guests to get lost within.

Asia’s third CMSCA Studios theme park opened with a bang in 2021. It has roller coasters. It has tours. It has some of the most incredible fantasy worlds on this planet. Take a tour of Hogwarts at The Wizarding World of Harry Potter Attraction, or revisit everyone’s favorite Kevin Costner film at Waterworld: A Live Sea War Spectacular. Universal Studios Beijing has something for everyone.

74. Russky Bridge

Location: Vladivostok, Russia
Total Cost: $1.1 Billion*
Year Finished: 2012
The Russky Bridge was built in order to connect Muravyov-Amursky Peninsula and Russky Island for the 2012 Asia-Pacific Economic Cooperation conference. Upon completion, the central span of Eastern Russia’s bridge measured just over 3,622 feet in length and 3390 yards from end to end — making it the longest cable-stayed bridge in the world. And one of the most expensive construction projects in history.

This $1.1 billion bridge was built to accommodate around 50,000 cars a day. However, in the decade since the conference took place, it has been seldom used for anything more than transporting tourists to and from the island.

75. Emirates Palace

Location: Abu Dhabi, U.A.E.
Total Cost: $3 Billion*
Year Finished: 2005
The 5-Star Emirates Palace was part of the first wave of the new magnificent architecture in the United Arab Emirates over the past few decades. This $3 billion hotel began welcoming guests in 2005 and has been living up to its reputation as a ‘palace’ ever since.

Most of the hotel’s 394 rooms have either marble or gold furnishing, sometimes both. The property has two helipads — just in case — and a private beach of almost 1-mile in length. If you need to take an afternoon away from the holiday in order to conduct some business, the palace also has forty rooms designated specifically for meetings.

76. Olkiluoto Nuclear Power Plant

Location: Eurajoki, Finland
Total Cost: $12.4 Billion*
Year Finished: 2021
Owned and operated by the Finnish nuclear power company Teollisuuden Voima (TVO), the Olkiluoto Nuclear Power Plant has been up and running since the late-1970s. In 2000, however, after having run smoothly for two decades TVO sent the Finnish government an application for the approval of an additional reactor unit.

The unit was approved in 2002 and construction began three years later. A few unexpected delays postponed the new unit’s inauguration, but it officially began producing electricity on March 12, 2022. So far, Finland’s nuclear power plant has cost more than $12 billion, and there are still provisional plans for at least one more reactor down the line.

The French Baroque building has been at the center of some very important historical events, not just for the French monarchy, but also for the world at large. For example, in 1919, it was the place where a world peace treaty was signed to declare the end of World War I. Its role in the Paris Peace Conference thrust it into global prominence once again.

79. Tokyo Imperial Palace

Location: Tokyo, Japan
Total Cost: $852 billion*
Year Finished: 1968
The Tokyo Imperial Palace is located in Tokyo, Japan, and it was the main residence of Japanese Emperors since the 1800s. It is estimated, according to Northwestern University, that the Tokyo Imperial Palace itself cost around $852.5 billion, adjusting for inflation. That’s a huge price tag for just one building.

If you take the Ginza office space as your reference point, this cost balloons into the trillions. At one point, during the Japanese property bubble in the eighties, the Palace was worth more than all of the real estate in California combined. Thousands visit this Palace every year to see its stunning architecture, beautiful gardens, and lovely grounds.

80. La Leopolda

Location: Villefranche-sur-Mer, France

Villa Leopolda overlooks the beautiful French Riviera lagoons, and it has had a colorful history, to say the least. During World War I, it was used as a French military hospital before it once again became a residence. You can also see this Villa in several famous movies, including The Red Shoes and To Catch a Thief. 

81. The Duchy of Cornwall

Location: Cornwall, England

The Duchy is one of the most well-managed private estates in the world.

It was originally founded by King Edward III, who provided it to his son, Prince Edward, in a charter in order to grant the prince his independence. Over the centuries, the Duchy has continued to work in much the same way, passing from generation to generation. 

82. Epcot

Location: Orlando, Florida
Total Cost: $800 million-$1.4 billion*
Year Finished: 1982

It is estimated that this theme park, with its country-based attractions, themed festivals, and international cuisine, cost anywhere from $800 million to $1.4 billion to construct.

Disney has certainly been able to recoup that investment, as it makes $1 million per day from ticket sales alone. All in all, its parks bring in $25 million per day, and Disney’s operating revenue is $5 million a day. It’s easy to see why Disney is considered a “blue chip” stock in which to invest.

The complex is very swanky, and it is host to occupants like Saudi billionaire Fawaz Alhokair and financier Lewis Sanders. Alkohair purchased the top-floor unit of the building for $88 million in 2016. For everyone else, the average unit in this pricey complex costs just below $17 million.
