In the summer of 1976, a ground fire burned through a vegetated area on the island of Guernsey, revealing a granite slab protruding from a high mound of earth. The ensuing excavation revealed an undisturbed 6,500-year-old burial site now named Les Fouaillages — one of the oldest monuments ever discovered in western Europe.
Ancient structures are discovered every year, adding to our understanding of human cultural evolution. Many of the oldest structures in existence had religious significance. These include tombs where bodies were interred with items intended to assist their owners in the afterlife, temples dedicated to the deities that a particular culture revered, and altars where animals and possibly even humans were sacrificed. (Here are ancient civilizations that have sacrificed humans.)
24/7 Tempo has compiled the 30 oldest structures in the world by consulting a number of archaeological, engineering, historical, and general interest websites, including World Archaeology, Realm of History, and Smithsonian Magazine.
Some sites date back to the Paleolithic era, which began some 2.5 million years ago and lasted until around 10,000 B.C. The era is marked by hunter-gatherer societies who used chipped stone and bone tools. Most sites, however, were built during the following Neolithic era, during which nomadic societies began to settle in permanent or semi-permanent locations and also began to refine their stone tools.
During this time, animal domestication and agriculture sprouted up independently in numerous societies. Some of the oldest structures in the world include tombs and burial mounds, religious temples, protective walls, and even entire cities. Here are the oldest continuously inhabited cities in the world.

Ngunnhu Fish Traps of Brewarrina
> Year built: circa 38000 B.C.
> Location: Brewarrina, New South Wales, Australia
> Purpose: Fish traps
Potentially the oldest human construction in existence, these ancient stone walls built by Australian Aboriginal people in the Barwon River were damaged considerably when Europeans began to colonize the area. An Aboriginal legend attributes the creation of the fish traps to the sky god Baiame.

Theopetra Cave Wall
> Year built: circa 21000 B.C.
> Location: Theopetra Cave, Thessaly, Greece
> Purpose: Barrier against the wind
This wall protects the entrance to a cave used by Paleolithic people during the last ice age. Built of stone in dry masonry fashion, the wall likely helped keep the cold out of the cave, which consists of a 5,382 square foot cavern. Evidence of earlier Neanderthal activity in the cave dates back 135,000 years.
Tell Qaramel
> Year built: circa 11000-9670 B.C.
> Location: Aleppo Governorate, Syria
> Purpose: Settlement
This Neolithic archaeological site contains the earliest known permanent stone-built settlement in the world. The site includes the remains of five stone towers, the oldest of which contains a raised hearth surrounded by benches. Evidence from the site suggests that the original settlement predates grain agriculture and animal domestication — the usual factors that spawned settlements — and that the settlement may have started instead because of religious ceremonies.
Ruins at Göbekli Tepe
> Year built: circa 9500-8500 B.C.
> Location: Southeastern Anatolia, Turkey
> Purpose: Unknown
Predating the development of metal tools, pottery, and agriculture, this ancient Neolithic site of massive stone megaliths that are arranged in circles may be the oldest temple in the world. The pillars are carved with human likenesses and weigh up to 10 tons each.

Wall of Jericho
> Year built: circa 8000 B.C.
> Location: Tell es-Sultan/Tel Jericho, West Bank, Palestinian Territories/Israel
> Purpose: Defensive barrier or flood protection
Likely built to protect the Neolithic settlement from floodwaters, the wall at Jericho was originally nearly 12 feet high and over 5 feet wide. Jericho is considered the oldest walled city in the world and is one of the oldest continually occupied cities as well. The original dwellings within the wall were circular homes made of clay and straw bricks.
Tower of Jericho
> Year built: circa 8000 B.C.
> Location: Tell es-Sultan/Tel Jericho, West Bank, Palestinian Territories/Israel
> Purpose: Unknown
Within the wall of Jericho is a massive stone tower with 22 steps ascending the interior. The conical tower is 28 feet high and may have had a communal or ceremonial function in the early settlement. It is estimated that the stone structure took 11,000 days to build.

Çatalhöyük
> Year built: circa 7500 B.C.
> Location: Konya province, Turkey
> Purpose: Settlement
This large Neolithic settlement was occupied between 7500 and 6400 B.C., likely peaking around 7000 B.C. with 10,000 inhabitants. The mud brick dwellings and other buildings are clustered together with no alleys or walkways between them. Instead, interior access was gained through holes in the roofs, and rooftops were likely used as streets and as a stage for daily activities.
Khirokitia
> Year built: circa 7000 B.C.
> Location: Larnaca, Cyprus
> Purpose: Settlement
One of the best preserved pre-pottery Neolithic settlements in the Mediterranean, Khirokitia was likely occupied from the seventh to fourth millennium B.C. The village was completely surrounded by a thick stone wall, and the foundations for the round living structures within the wall were also made of stone. Multiple huts arranged around a central courtyard are thought to have comprised a single home, with each hut used for different activities.
> Year built: circa 5500 B.C.
> Location: Dobrich Province, Bulgaria
> Purpose: Settlement
On an island in Durankulak lake, this large Neolithic settlement contains numerous stone buildings, including one of the largest prehistoric stone buildings in Europe, at over 2,000 square feet. Homes were large with several rooms in each building. The people who built these structures were not only excellent stone workers, but they were also one of the first cultures to smelt copper and gold into jewelry.

Perperikon
> Year built: circa 5000 B.C.
> Location: Kardzhali Province, Bulgaria
> Purpose: Settlement
Although the city of Perperikon saw many incarnations as it went from Thracian to Roman to Byzantine rule, the earliest human traces date back to the fifth millennium B.C. One of the oldest structures there is a round altar nearly 6 feet in diameter that was carved out of rock. The sanctuary was carved out of the mountain in the late Bronze Age, and many archaeologists believe it may have been used as a temple of Dionysus.

> Location: Guernsey, Channel Islands, English Channel
> Purpose: Burial ground
An ancient burial site discovered in 1976, this excavated mound contains a stone structure that is most likely the remnants of a tomb, where shards of pottery suggest funerary offerings were made. Another structure there was likely used as a shrine.
Sechin Bajo
> Year built: circa 3600 B.C.
> Location: Ancash, Peru
> Purpose: Settlement
Situated on the arid Peruvian coast, the Sechin Bajo site is possibly a remnant of the oldest civilization in the Americas.

The temple was coated with gypsum and was used for religious rituals. The ziggurat was first built in 4000 B.C. and underwent 14 subsequent phases of additional construction.
Monte d’Accoddi
> Year built: circa 4000-3650 B.C.
> Location: Sassari, Sardinia, Italy
> Purpose: Temple or altar
Presumed to be an altar or temple, this raised stone platform on the island of Sardinia was initially built around 4000 B.C., then destroyed around 3000 B.C., and rebuilt with limestone into a step pyramid resembling a ziggurat. Remains of sheep, pig, and cow sacrifices have been excavated from the site, making it one of the earliest known religious monuments in the Western Mediterranean.

> Location: Various locations, Malta
> Purpose: Temples
Multiple megalithic temples built between 3600 B.C. and 2500 B.C. on the island of Malta provide evidence of the cultural and architectural evolution of the Neolithic peoples who built them. They are among the oldest free-standing stone buildings in the world and share several key similarities, including ovular forecourts, stone post entryways, and D-shaped chambers.

The oldest network of earthen mounds in North America, these Middle Archaic structures were built and utilized over centuries by a hunter-gatherer culture. The site contains 11 mounds (ranging from 3 to 25 feet high) connected by ridges and forming a 900-foot oval. Deposits in the strata suggest that the area was used as a base for the nomadic culture from summer through fall.
