Started in 1978, the UNESCO World Heritage List now recognizes over 1,000 sites in more than 165 states for having outstanding cultural, historical, or scientific significance to humanity. After being designated to the list, each site is protected for all time against degradation and development.

UNESCO World Heritage sites range from historic buildings like churches and archaeological sites to natural sites like Yellowstone National Park and the Galápagos Islands, and you could easily spend a lifetime visiting every one of them. To get you started, we’ve pulled 10 must-see European archeological sites from the list, including temples, Viking monuments, stone circles, and cave paintings, ranging from 450,000 years old to the 13th century.

  • When it dates back to: 50,000 BCE
  • When it became a UNESCO World Heritage site: 1992
  • Address/location: SH81, Butrint, Albania
  • What you need to see there: The Greek theater, which once held 2,500 people and is known for its impressive number of stone inscriptions.

Butrint was the first Albanian site to make the UNESCO World Heritage List in 1992. The site is a microcosm of Mediterranean history, having been inhabited as early as 50,000 BCE, and in more recent centuries serving as a Greek colony, a Roman city, and a diocese (an area controlled by a bishop.)

According to Roman writer Virgil, Butrint, or Bouthroton to the ancient Greeks, was founded after the fall of Troy by King Priam’s son, and Greek historian Hekateus claimed that the city was modeled after Troy itself. Butrint today bears all of the elements of a Greek polis, including a well-preserved theater and an agora. Later Roman aqueducts, baths, and a forum can be found, as well as an early-Christian baptistery with a magnificent mosaic floor.

After the fifth century CE, Butrint became a fortified diocese, and a basilica was built. Byzantines held the city until the 13th century, then Venetian merchants until it was abandoned in the 16th century when nearby marshes began encroaching on the city.

The European archeological site of Butrint is 12 miles from Saranda, close to the Greek border. There are hydrofoil day trips from the Greek island of Corfu to Saranda, with buses from the city to Butrint.

  • When it dates back to: 900 CE, with a church dating to 1100 CE
  • When it became a UNESCO World Heritage site: 1994
  • Address/locations: Thyrasvej 1, 7300 Jelling, Denmark
  • What you need to see there: The runic stone situated between two burial mounds that proclaims the Christianization of Denmark.

Considered by many Danes to mark the location of the creation of Denmark as a nation state, the Jelling Mounds and Runic Stones World Heritage Site are an incredible example of pagan Nordic culture and early Nordic Christianization.

The site was a royal monument and seat of power during the reigns of Danish kings Gorm and Harald Bluetooth. Two 10th century mounds, 200 feet in diameter and 20 feet tall, dominate the site, one containing a burial chamber of oak. A beautiful runic stone between the mounds was erected by Harald Bluetooth to proclaim his introduction of Christianity to Denmark and his integration of Norway into his kingdom, and features the earliest depiction of Christ found in Scandinavia. There is also a simple church of whitewashed stone dating to 1100 on site, with frescoes inside dating to 1125. The church was built on the site of three earlier churches, one of which was raised by Harald himself.

The Jelling Mounds are located in central Jutland, three hours east of Copenhagen. You can also fly into the town of Billund and take a one hour bus to the site.

  • When it dates back to: Sparsely inhabited from 8,000 BCE, with 13th century hillforts
  • When it became a UNESCO World Heritage site: 2004
  • Address/locations: Kerniaus g. 4A, Kernavė 19172, Lithuania
  • What you need to see there: The five hillforts of Kernavė, which provide beautiful views of the former medieval capital of Lithuania.

Kernavė, located in eastern Lithuania, features evidence of over 10,000 years of human settlement, from the Paleolithic to the Middle Ages. The archaeological site today is dominated by five massive hillforts, created when Kernavė was a Christian feudal town in the 13th century. At the time, Kernavė was the medieval capital of the Grand Duchy of Lithuania, and served as an important hub for craftsmen and merchants, until it was destroyed by the Teutonic Order during the Lithuanian Civil War in the 14th century. The wet peat in the valley covered the remains of the city and provided unusually good preservation; the oldest known medgringa, a secret, underwater road through the swamps, was found in Kernavė, dating to the fourth century.

There is a museum on site that has presentations on Kernavė’s long history, and an open-air area with a rebuilt section of the medieval town, constructed using medieval techniques.

The European archeological site of Kernavė is 21 miles northwest of Vilnius and can be reached by bus.

The valley has a further 25 decorated caves and 147 prehistoric sites dating from 450,000 to 9,000 years ago, making for an unusually rich archeological site that is unparalleled anywhere in the world.

Twelve caves are open to a limited number of visitors every day, including Rouffignac Cave, the longest cave system in the region. An electrical train ferries visitors through the cave, where hundreds of engravings and monochrome paintings can be seen. Visitors can also visit the Cro-Magnon Shelter where, in 1868, the skeletons of five ancestral humans, dating from between 10,000 and 35,000 years ago and distinct from Neanderthals, were found. While Lascaux is closed to the public, there are extensive 3D reproductions easily accessible.

The nearby town of Les Eyzies can be reached by train from Bordeaux, however the valley is large and the sites are difficult to access without a car.

  • When it dates back to: Sixth century BCE
  • When it became a UNESCO World Heritage site: 1987
  • Address/locations: Delphi 220 54, Greece
  • What you need to see there: The Temple of Apollo and the Sacred Way, which is lined with votive statues and treasury buildings.

The sanctuary of Delphi, situated at the foot of Mount Parnassos, was the religious center of the Greeks during the sixth century BCE. Delphi was known to the Greeks as the omphalos, or navel of the world, and was visited by pilgrims throughout the Mediterranean. Many of them came to consult the Oracle of Delphi, a priestess living at the sanctuary who supposedly communed with the god Apollo and relayed his messages to the public. The priestess was consulted before any Greek colony was founded, and had immense power over political and military decisions.

Delphi is a monumental complex, featuring temples to Athena, treasury buildings, and the sanctuary to Apollo, where the priestess delivered her messages. Delphi was also the site of several Greek games and contests, and has gymnasiums, theaters, and stadion.

This European archeological site is 110 miles northwest from Athens, connected to the capital by bus. The town itself has numerous hotels and restaurants.

  • When it dates back to: 3,000 BCE
  • When it became a UNESCO World Heritage site: 1993
  • Address/locations: Glebe, Donore, Co. Meath, A92 EH5C, Ireland
  • What you need to see there: Newgrange’s megalithic passage tomb, the largest one in Ireland.

Brú na Bóinne in Ireland is Europe’s largest and most important example of megalithic art. The site was referenced in works of early Irish literature, and was believed to have been where the Tuatha Dé Danann, a race of supernatural beings similar to elves, lived. Three massive burial mounds built 5,000 years ago dominate the site, while forty satellite passage graves surround the nearby area, creating a massive funerary and ritual landscape older than the Egyptian pyramids.

The area is divided into three groups, Knowth, Newgrange, and Dowth; Knowth has thirty monuments from Neolithic to Anglo-Norman, while Newgrange has the largest megalithic passage tomb in Ireland, and Dowth has occupation evidence through the Middle Ages. Each group also features megalithic art in the form of beautifully carved stones. The entire area was used for rituals, gatherings, and for the living to connect with the dead.

There is a visitor center in the Boyne river valley that features a full-scale replica of the Newgrange chamber and provides tours to the Newgrange burial mound itself.

The site is 30 miles north of Dublin, and there are trains and buses to the nearby town of Drogheda.

  • When it became a UNESCO World Heritage site: 1998
  • Address/locations: Côa Valley, R. do Museu, 5150-610 Vila Nova Foz Côa, Portugal; Siega Verde, DSA-470, km 26, 400, 37488 Villar de la Yegua, Salamanca, Spain
  • What you need to see there: A kayak tour down the Côa River to see the best of the rock art panels, as well as the birds and otters that call the valley home.

Côa Valley and Siega Verde are two separate sites that straddle the border between Portugal and Spain; Côa Valley is in Portugal and Siega Verde is in Spain. Both sites are considered to be the best open-air ensembles of Paleolithic art on the Iberian Peninsula. Dating from 20,000 BCE to 7,000 BCE, the sites contain hundreds of panels of animal and anthropomorphic figures that were carved and picked into the cliffs.

In 1995, a new dam on the Côa River was proposed that would have flooded the lower levels of the river valley and large areas of the site. World interest in saving the site mobilized anti-dam campaigns in Portugal, as well archaeologists and UNESCO. In 1998, the sites were designated as World Heritage Sites.

The sites are one hour and fifteen minutes apart, and Côa Valley is two hours from Salamanca, Spain. There is a visitor center and museum in Côa Valley, where you can take a guided 4×4 tour or a kayak trip down the Côa River to see the sites.
