A new study of the world-famous Inca citadel of Machu Picchu has led scientists to believe the Unesco World Heritage Site is at least 20 years older than previously thought.
For many years, historians have assumed the site in south Peru was built some time after 1438 AD. This was based primarily on 16th-century Spanish accounts from their conquest of the region.
But now, new radiocarbon dating techniques carried out at the site suggest the citadel was occupied from around 1420 AD, almost two decades earlier.
"This is the first study based on scientific evidence to provide an estimate for the founding of Machu Picchu and the length of its occupation," said Richard Burger, a professor of anthropology at Yale University who led the research.

“The results suggest that the discussion of the development of the Inca empire based primarily on colonial records requires revision.”
Burger and his team used accelerator mass spectrometry (AMS) dating of human remains to come to the conclusion. The team looked at 26 individuals from cemeteries at Machu Picchu that were recovered from the site during excavations in 1912.
The findings were published in the peer-reviewed journal Antiquity.
Voted one of the New Seven Wonders of the World in 2007, Machu Picchu was declared a World Heritage Site by Unesco in 1983. A hugely popular tourist destination, it received more than half a million visitors a year before the coronavirus pandemic.
In 2017, Peruvian authorities sought to protect the site by introducing ticketed time slots to control the flow of visitors at the settlement.
Perched between two mountains, the site is made up of roughly 200 stone structures, which include remains of a ceremonial bathhouse, temples, granaries and aqueducts.
Believed to have been built as a palace for Inca emperor Pachacuti, it was abandoned around 1572 AD as a consequence of the Spanish invasion of Inca lands. The site was not found by the colonisers, although it was always known to the locals, until American explorer Hiram Bingham brought it to international attention in 1911.
In October 2020, the site opened to the public for the first time after months of closure owing to the pandemic. Its first visitor was a Japanese tourist who was stranded in Peru.

- Promises of high, fixed or 'guaranteed' returns.
- Unregulated structured products or complex investments often used to bypass traditional safeguards.
- Lack of clear information, vague language, no access to audited financials.
- Overseas companies targeting investors in other jurisdictions - this can make legal recovery difficult.
- Hard-selling tactics - creating urgency, offering 'exclusive' deals.

10 tips for entry-level job seekers
- Have an up-to-date, professional LinkedIn profile. If you don’t have a LinkedIn account, set one up today. Avoid poor-quality profile pictures with distracting backgrounds. Include a professional summary and begin to grow your network.
- Keep track of the job trends in your sector through the news. Apply for job alerts at your dream organisations and the types of jobs you want – LinkedIn uses AI to share similar relevant jobs based on your selections.
- Double check that you’ve highlighted relevant skills on your resume and LinkedIn profile.
- For most entry-level jobs, your resume will first be filtered by an applicant tracking system for keywords. Look closely at the description of the job you are applying for and mirror the language as much as possible (while being honest and accurate about your skills and experience).
- Keep your CV professional and in a simple format – make sure you tailor your cover letter and application to the company and role.
- Go online and look for details on job specifications for your target position. Make a list of skills required and set yourself some learning goals to tick off all the necessary skills one by one.
- Don’t be afraid to reach outside your immediate friends and family to other acquaintances and let them know you are looking for new opportunities.
- Make sure you’ve set your LinkedIn profile to signal that you are “open to opportunities”. Also be sure to use LinkedIn to search for people who are still actively hiring by searching for those that have the headline “I’m hiring” or “We’re hiring” in their profile.
- Prepare for online interviews using mock interview tools. Even before landing interviews, it can be useful to start practising.
- Be professional and patient. Always be professional with whoever you are interacting with throughout your search process, this will be remembered. You need to be patient, dedicated and not give up on your search. Candidates need to make sure they are following up appropriately for roles they have applied.
