Top 10 Oldest Things Still in Use
Throughout human history, countless inventions, structures, and practices have come and gone, yet remarkably, some creations from our ancient past continue to serve their original purposes today. These enduring artifacts and institutions stand as testaments to human ingenuity and the timeless nature of certain innovations. From ancient architectural marvels to everyday objects, these ten oldest things still in use demonstrate that good design and solid construction can truly stand the test of time, surviving millennia while maintaining their relevance and functionality in our modern world.
1. The Pantheon in Rome (126 AD)
The Pantheon remains one of the best-preserved ancient Roman buildings and has been in continuous use for nearly 2,000 years. Originally built as a temple to all Roman gods, it was converted into a Christian church in 609 AD, which likely saved it from destruction. The building's massive concrete dome, still the world's largest unreinforced concrete dome, showcases Roman engineering prowess. Today, the Pantheon serves as both a functioning church and one of Rome's most visited tourist attractions, hosting religious services and serving as a burial place for important Italian figures, including the artist Raphael.
2. The University of Al Quaraouiyine (859 AD)
Located in Fez, Morocco, the University of Al Quaraouiyine holds the Guinness World Record as the oldest existing, continually operating educational institution in the world. Founded by Fatima al-Fihri, a young princess from Tunisia, it began as a mosque and gradually developed into one of the leading spiritual and educational centers of the Muslim world. For over 1,100 years, it has continuously provided education to students, initially focusing on Islamic studies and Arabic grammar, and later expanding to include mathematics, astronomy, medicine, and philosophy. The university still operates today, maintaining its commitment to education while preserving its historical significance.
3. The Crypt of the Capuchins in Rome (1631 AD)
While not as ancient as some entries on this list, the Crypt of the Capuchins represents a unique and continuously used burial site that has maintained its original purpose for nearly 400 years. The crypt contains the skeletal remains of 3,700 bodies of Capuchin friars, artistically arranged in elaborate decorative patterns throughout five small chapels. This ossuary beneath Santa Maria della Concezione dei Cappuccini church remains an active place of reflection and prayer, reminding visitors of mortality while continuing to serve its spiritual purpose as intended by its creators.
4. The Aqueduct of Segovia (98 AD)
This magnificent Roman aqueduct in Spain transported water for nearly 2,000 years, only ceasing operation in the late 19th century for its original purpose. However, it remains "in use" as a functioning historical monument and the symbol of Segovia. The aqueduct's 167 arches stretch over 800 meters and stand up to 28 meters tall at its highest point, constructed without any mortar—just perfectly fitted granite blocks. While no longer carrying water, the structure continues to inspire architects and engineers worldwide, demonstrating Roman engineering excellence and serving as a vital part of the city's infrastructure as a tourist landmark and cultural icon.
5. The Door of the Basilica di San Lorenzo Fuori le Mura (Pre-13th Century)
Some of the oldest working doors in the world can be found at various churches throughout Europe, with notable examples at the Basilica di San Lorenzo Fuori le Mura in Rome. These ancient wooden doors, some dating back over 1,800 years, continue to swing open and closed, welcoming worshippers just as they have for centuries. The longevity of these doors speaks to the quality of craftsmanship and the durability of properly maintained wood. These portals serve not only as functional entryways but also as tangible connections to the countless generations who have passed through them.
6. The Tower of Hercules Lighthouse (1st Century AD)
Standing proudly on the coast of Galicia, Spain, the Tower of Hercules is the oldest lighthouse still in use today. Built by the Romans in the 1st century AD, this 55-meter tall structure has been guiding ships safely to shore for approximately 1,900 years. While the lighthouse has undergone various renovations and modifications over the centuries, including a major restoration in the 18th century, its Roman core remains intact. The tower was designated a UNESCO World Heritage Site in 2009 and continues to operate as a fully functional lighthouse, making it an extraordinary example of ancient engineering that still serves its original purpose.
7. The Jeweled Ceiling of the Basilica di Santa Maria Maggiore (5th Century)
While the entire Basilica di Santa Maria Maggiore in Rome dates to the 5th century and remains in active use as a papal basilica, its stunning coffered ceiling is particularly noteworthy. Gilded with some of the first gold brought back from the Americas, the ceiling has been continuously admired by worshippers and visitors for over 1,500 years. The basilica itself has never closed and continues to hold daily masses, making it one of the oldest churches in continuous operation, housing some of the oldest Christian art and architecture still serving their original devotional purposes.
8. The Pont du Gard Aqueduct (1st Century AD)
This ancient Roman aqueduct bridge in southern France, built in the 1st century AD, stands as one of the best-preserved Roman monuments. While it no longer carries water as originally intended, the structure remains very much "in use" as a bridge and vital historical monument. For centuries after the fall of the Roman Empire, locals continued to use the lower tier as a bridge to cross the Gardon River, and pedestrians still walk across its span today. The Pont du Gard serves as an educational resource, tourist destination, and testament to Roman hydraulic engineering, demonstrating how ancient infrastructure can adapt to serve new purposes across millennia.
9. The Baths of Caracalla's Underground System (216 AD)
While the grand Roman baths no longer function as a bathing complex, parts of the underground heating and water system (hypocaust) have been studied and some elements remain intact and observable, serving educational purposes. More significantly, the ancient venue has been repurposed and is still "in use" as a spectacular summer opera venue, with the Rome Opera performing within these ancient walls. This adaptive reuse allows the structure to continue serving the public, albeit in a dramatically different capacity than originally intended, showing how ancient spaces can evolve while maintaining their public service mission.
10. The Caravan Bridge at Izmir (850 BC)
Turkey's ancient stone bridges represent some of the oldest continuously used infrastructure in the world. While many ancient bridges exist, several in Turkey that date back thousands of years continue to carry foot traffic and, in some cases, even light vehicle traffic. These bridges, originally built to facilitate trade routes, particularly the caravan bridge near Izmir that dates to approximately 850 BC, demonstrate exceptional engineering that has withstood earthquakes, floods, and the passage of time. Their continued use underscores the sophistication of ancient civil engineering and the durability of well-planned stone construction.
Conclusion
These ten remarkable examples of humanity's oldest creations still in use today demonstrate that exceptional craftsmanship, thoughtful design, and solid engineering can transcend time. From the continuously operating University of Al Quaraouiyine to the still-functioning Tower of Hercules lighthouse, from Rome's eternally open Pantheon to ancient bridges still bearing traffic, these structures and institutions connect us directly to our ancestors. They serve as reminders that while technology and societies evolve, fundamental human needs for education, spiritual connection, infrastructure, and community gathering spaces remain constant. These ancient marvels continue to enrich our lives, proving that the best innovations are not merely products of their time but timeless gifts to future generations.
