Located in the southeast Pacific, Rapa Nui, or Easter Island , is best known as the home of approximately 1,000 giant "head" statues, or moai. There are an estimated 900 moai on Rapa Nui, which were carved and erected sometime between the 11th and 17th centuries A.D., according to UNESCO . The figures, which consist of oversized heads atop long torsos, range in height from 6 feet (2 meters) to over 30 feet (9 m), though one unfinished moai on the island is over 65 feet (20 m) tall.
The moai, and the ceremonial platforms (ahu) around which they typically stand, were built by a group of Eastern Polynesian settlers, who came to the island sometime around the first century A.D. The Rapa Nui people worshiped their ancestors and depended on these ancestral gods for protection and good fortune during life and the afterlife, according to the Easter Island Statue Project . Researchers believe that the moai were constructed as representations of these deified ancestors.
Antikythera Mechcanism

In 1900, a group of sponge divers in the Mediterranean Sea came across a 2,000-year-old shipwreck off the Greek island of Antikythera. The divers hauled many artifacts from the wreck, including three flat pieces of corroded bronze that are now known as the Antikythera Mechanism .
The rusty old device sat in storage at the National Archaeology Museum, Athens, until the 1950s, when Derek J. de Solla Price, a science historian from Yale University, took interest in the find. Price described the mechanism as an "ancient Greek computer," and other researchers have referred to the Antikythera Mechanism as an astronomical calculator . It's about the size of a shoebox and contains an intricate system of gears and a crank on the outside that controls the gears. The two faces of the device contain a series of dials, which researchers believe corresponded to a display of the sun, moon and planets
While the ancient Greeks could have used the device to track the position of the sun, the phases of the moon and even the cycles of Greek athletic competitions, researchers aren't sure why ancient people would have needed such a complicated device to track those cycles. Recently, researchers have suggested that the Antikythera Mechanism was used as an instructional device — more of a novelty than a necessity.
Nazca Lines
The animal mounds were found in a region famous for a series of ancient geolyphs, called the Nazca Lines, which are now considered a World Heritage Site in the Nazca Desert in southern Peru. Here, Nazca Lines resembling a humming bird, as viewed from a plane. (Image credit: )
The Nazca Lines are geoglyphs (large designs produced on the ground) located on the coastal plateau of Peru. The designs, many of which were scratched on the ground or created with rocks, cover about 170 square miles (450 square kilometers). The oldest of the lines were made with rocks and date to 500 B.C., but the ancient Nazca people produced most of the designs between 200 B.C. and A.D. 500. Some of the Nazca Lines are simple geometric shapes, while others are in the shape of animals, like monkeys, birds and llamas.
The mysterious lines were never really "discovered," as they are visible from nearby foothills, and many people likely observed them before they were brought to the attention of the general public. Paul Kosok, a historian from the U.S., was the first researcher to seriously study the Nazca Lines in the 1940s. To this day, researchers aren't sure why the lines were made. However, there are a number of theories as to their possible uses, including those that suggest links to astronomy, religion and agriculture. [See Photos of the Mysterious Nazca Lines ]
Voynich Manuscript
The Voynich manuscript has eluded interpretation for a century. It was written in Central Europe in the 15th century and rediscovered by antique book dealer in 1912. Despite intense scrutiny, no one has been able to read the mysterious script. (Image credit: Public domain) An antique dealer discovered the mysterious Voynich Manuscript in 1912 and immediately knew that he had stumbled upon something special — a book written in a language that no one can read. The 250-page book features a range of interesting images, from female nudes and Zodiac signs to drawings of medicinal plants.
Researchers believe that the book is about 600 years old and hails from Central Europe. One researcher who has studied the Voynich manuscript extensively believes that it is most likely a treatise on nature, written in an unknown Near Eastern or Asian Language. However, there are some scholars who believe that the manuscript is simply an elaborate hoax that has kept people guessing since the Renaissance.

Gobekli Tepe
Located in southern Turkey, near the modern-day city of Urfa, Göbekli Tepe is an archaeological site that dates back more than 11,000 years. Only a small portion of the site has been excavated since its discovery in 1963, but researchers believe that the structures found there may have been part of a prehistoric temple — perhaps the first temple ever constructed.
Göbekli Tepe's standout features are its T-shaped limestone blocks, which line the site's stone rings. The rings were built so that each was inside of the other and the largest has a diameter of 100 feet (30 m). Before building a new ring inside of a larger ring, ancient people would line the outer ring with the T-shaped blocks and then fill the outer ring with debris. The blocks were also carved with images of people and animals. While researchers aren't sure exactly what purpose all of these rings and blocks served, some suspect that the site attracted people from all over the Near East and served as a place of pilgrimage .
Staffordshire hoard

In 2009, a man in Staffordshire, England, quite literally struck gold while taking a stroll through the countryside. The man was using a metal detector in a recently ploughed field when he happened upon the largest Anglo Saxon treasure hoard ever discovered.
Archaeologists excavated the hoard, recovering more than 3,500 items made from gold, silver and other metals. Among these items are thousands of pieces of garnet cloisonné jewelry (gold items with inlaid garnet, a red gemstone), golden sword pommels and crosses. Most of the artifacts that make up the hoard are "martial" in nature, or have something to do with warfare, and none of the items are domestic goods, like cups or silverware. This leads researchers to believe that the treasure may have been part of a "death duty," or a collection of valuable gifts that were given to a king upon the death of one of his noblemen.
Most of the items in the Staffordshire hoard date back to the seventh century A.D., and many of the treasures are on display at the Birmingham Museum and Art Gallery and the Potteries Museum and Art Gallery in the U.K.
Provincial pyramids of Egypt

You've heard of the Great Pyramid of Giza , but what about the step pyramid of Edfu ? This ancient structure is about 4,600 years old, making it at least a few decades older than the famous pyramid at Giza.
The once 43-foot-tall (13 meters) step pyramid is one of seven "provincial" pyramids constructed by either pharaoh Huni or Snefru sometime between 2635 and 2590 B.C. These early pyramids are found throughout central and southern Egypt near what were once major settlements. Unlike the pyramids at Giza, the step pyramids do not contain internal chambers and weren't used for burial. In fact, researchers aren't sure what their primary purpose was.
Scholars knew about the pyramid at Edfu long before it was first excavated in 2010. However, recent efforts by archaeologists from the University of Chicago are the first to explore in-depth the reasons for the pyramid's construction and subsequent abandonment not long thereafter.
Madaba Map

The Madaba map is the oldest surviving map of the Holy Land (particularly Jerusalem) and is part of a floor mosaic in the Byzantine church of Saint George in Madaba, Jordan. The map was uncovered during renovations at the church in 1884 and dates to somewhere between 560 and 565 A.D. [The Holy Land: 7 Amazing Archaeological Finds ]
While the map originally depicted a large swath of the Middle East, from southern Syria to central Egypt, much of the mosaic map was already destroyed when it was first uncovered. However, the part of the map depicting Jerusalem remained in tact and includes an oval-shaped walled city with six gates, 21 towers and several dozen buildings and structures.
Visitors to Madaba can see the map in person, and a copy of the ancient map is also kept at the Archaeological Institute at Göttingen University in Germany.
The grave of Richard III

After centuries of speculation, the grave of King Richard III was finally unearthed in 2012 by archaeologists at the University of Leicester in England. The king, who was immortalized (for better or for worse) in Shakespeare's play "Richard III," died in battle in 1485. Rather than a regal funeral, King Richard's body was reportedly interred at the church of the Grey Friars in Leicester, the location of which was lost to history.
But using historical records, archaeologists were able to narrow down the former location of the church and recover the bones of the late king. In 2015, Richard III was reburied in a marble tomb next to the altar in Leicester Cathedral.
