In this article, we will be taking a look at the 17 oldest buildings in the world that are still in use. If you want to skip our detailed analysis of the US construction industry and construction technologies, you can go directly to 5 Oldest Buildings In The World That Are Still In Use.

In today’s world, the construction industry contributes greatly to the economic growth of any country. Some of the oldest man-made structures in the world were built by manual labor with the use of basic tools and easily available materials. However, over the last few centuries, construction has undergone a remarkable transformation.

The US Construction Industry Continues To Show Promise Despite Near-Term Challenges

Economic uncertainties, inflation, and recessionary fears from 2022 continue to disrupt the macroeconomic environment in 2023, especially for the tech giants. Alphabet Inc. (NASDAQ:GOOG) announced in December 2022 that they have decided to halt construction activities of their $600 million data center project in Minnesota. Meta Platforms, Inc. (NASDAQ:META), also in December 2022, made a similar announcement about their new data center in Idaho, where construction activities had begun in September 2022. If such trends continue in 2023, the growth of the construction industry could slow down as a result.

Although the construction industry in certain sectors is facing short-term challenges, medium to long-term growth is expected to continue in the United States. The US construction industry is expected to increase by 6.1% to reach $1.42 trillion in 2023. According to Research and Markets, the construction industry is expected to grow at a compound annual growth rate (CAGR) of 5.2% from 2023 through 2027, propelling the US construction industry to reach a value of around $1.74 trillion by the end of the forecasted period.

As we mentioned in one of our previous articles, 20 Largest Construction Companies in the US, the construction industry in the US has been granted immense governmental funding and support. This could prove to be truly beneficial for the construction industry as well as for some of the top construction stocks such as Caterpillar Inc. (NYSE:CAT), Builders FirstSource, Inc. (NYSE:BLDR), and Lennar Corporation (NYSE:LEN).

On July 3, Reuters reported that there was a severe shortage of single-family homes which led to a surge in homebuilding projects in May 2023. Spending on private and residential construction accelerated beyond expectations helping the construction industry move in the direction of progress.

Lennar Corporation (NYSE:LEN), with their focus on growing their business, took notice of this opportunity. Here are some comments from its Q2 2023 earnings call:

“Looking ahead, we continue to believe that the market and the economy will remain constructive for home builders as pent-up demand continues to come to market and consume affordable offerings. Additionally, we believe that the supply constraint will continue to limit available inventory and maintain supply-demand balance. The core elements of the supply shortage will not resolve in the near term as the almost 15-year production deficit will take years to resolve. And note that even when existing homes with low-interest mortgages — even when existing homes with low-interest mortgages that are not currently trading, do come to the market and add to supply, the sellers will also need a place to move and that creates a net zero to overall dwellings, in addition to supply and in addition to demand and therefore still a housing shortage.

Bottom line, supply is short, demand is returning to affordable offerings and builders will need to produce more homes to fill the void.”

On June 14, Lennar Corporation (NYSE:LEN) reported strong earnings for the fiscal second quarter of 2023. The company reported earnings per share (EPS) of $2.94, surpassing EPS estimates by $0.62. The company reported a revenue of $8.05 billion and outperformed revenue estimates by $796.30 million.

Technology and Construction

Compared to other industries, the construction industry, defying the odds, has actually stepped out of the COVID-19 crisis in a better state of affairs. Advancements in engineering, machinery and architectural knowledge have the potential to change the construction industry forever.

UAVs and drones are helping construction companies by providing them with real-time aerial imagery and 3D lidar scans to revolutionize construction operations. According to a report by Visiongain, with a rising demand for drone services, the drone service market is projected to grow at a CAGR of 19.8% from 2023 through 2033.

Other promising and innovative technologies in construction across the globe include Building Information Modeling (BIM) which helps create more precise digital models of buildings while also offering good interoperability. According to a report by SNS Insider, the building information modeling industry was worth $6.85 billion in 2022 and is expected to grow to $17.32 billion by 2030, recording a CAGR of 12.3% over the forecasted period. 

3D Printing is perhaps the most widely known construction technology despite the fact that it is not as widespread as some of the other innovations. On January 12, Reuters reported that a two-story home was created with the help of a 3D printer in the United States. Engineers at Arup and CLS Architetti of Italy have also used 3D printing and demonstrated the potential of this technology to change all that we know about the construction process.

Our Methodology

We have listed the oldest buildings in the world that are still in use along with their respective locations. To collect data for our list, we used various sources including Grunge, Gizmodo, and loveExploring. In addition to these websites, we also consulted many more lists on the internet and cross checked construction dates and claims as to whether or not each of the buildings could be said to be functional or in use today.

For this list, we have excluded man-made structures that did not qualify as buildings as well as buildings that are not currently in use. We selected the buildings for our list by looking at the time they were built or established. For some of the oldest buildings in our list, there are differing opinions on the exact dates of construction as well as opening dates and so the time provided may be an estimation.

In the case of buildings that were established in the same year, tie breaking was done on the basis of the dates when construction had originally started for the buildings. The list below is in a reverse chronological order based on the construction dates of the buildings, from the newest to the oldest.

7. Mausoleum of Hadrian (Castel Sant’Angelo)

Construction Year: 139 AD

Location: Rome, Italy

The Mausoleum of Hadrian, completed in AD 139, was commissioned by the Roman Emperor Hadrian as a mausoleum for himself and his family. Also known as Castel Sant’Angelo, the towering cylindrical building was once the tallest building in Rome. Over the course of history, it has been used by the popes as a fortress and castle. However, the castle is now a museum filled with fascinating exhibits, attracting huge amounts of tourists to browse all five floors. Mausoleum of Hadrian is placed seventh among the oldest buildings in the world that are still in use.

6. The Pantheon

Construction Year: 125 AD

Location: Rome, Italy

The Pantheon was originally built by Marcus Agrippa between 25-27 BC as a Roman Temple. However, the temple burned down and the Pantheon as we know it today is a result of the radical reconstruction around 125 AD by the Roman Emperor Hadrian. This is also the reason why the Pantheon’s date of construction is often said to be 125 AD. Since the 7th century, this ancient Roman building has been used as a Church dedicated to St. Mary and the Martyrs. Now also known as “Santa Maria ad Martyres”, it welcomes visitors and continues to host special events as a Catholic Church.
