Well, there’s always Wiki:
Current locations
Since its disappearance from the Biblical narrative, there have been a number of claims of having discovered or of having possession of the Ark, and several possible places have been suggested for its location.
Mount Nebo
2 Maccabees 2:4-10, written around 100 BC, says that the prophet Jeremiah, “being warned by God” before the Babylonian invasion, took the Ark, the Tabernacle, and the Altar of Incense, and buried them in a cave on Mount Nebo (Jordan), informing those of his followers who wished to find the place that it should remain unknown “until the time that God should gather His people again together, and receive them unto mercy.” Mount Nebo is also described in the Bible (Deuteronomy 34) as the site from which Moses views the Promised Land, and apparently also is his final burial place. Mount Nebo (Jordan) is approximately 29 miles (47 km) slightly south of due east from Jerusalem, near the east bank of the Jordan River.
Ethiopia
The Chapel of the Tablet at the Church of Our Lady Mary of Zion in Axum allegedly houses the original Ark of the Covenant.
The Ethiopian Orthodox Church claims to possess the Ark of the Covenant, or Tabot, in Axum, not far from the border with Eritrea. The object is currently kept under guard in a treasury near the Church of Our Lady Mary of Zion and is used occasionally in ritual processions Replicas of the Axum tabot are kept in every Ethiopian church, each with its own dedication to a particular saint, the most popular of these include Mary, George and Michael.
The Kebra Nagast, composed to legitimise the new dynasty ruling Ethiopia following its establishment in 1270, narrates how the real Ark of the Covenant was brought to Ethiopia by Menelik I with divine assistance, while a forgery was left in the Temple in Jerusalem. Although the Kebra Nagast is the best-known account of this belief, the belief predates the document. Abu al-Makarim, writing in the last quarter of the twelfth century, makes one early reference to this belief that they possessed the Ark. “The Abyssinians possess also the Ark of the Covenant”, he wrote, and, after a description of the object, describes how the liturgy is celebrated upon the Ark four times a year, “on the feast of the great nativity, on the feast of the glorious Baptism, on the feast of the holy Resurrection, and on the feast of the illuminating Cross.”
On 25 June 2009, the patriarch of the Orthodox Church of Ethiopia, Abune Paulos, said he would announce to the world the next day the unveiling of the Ark of the Covenant, which he said had been kept safe and secure in a church in Axum, Ethiopia. The following day, on 26 June 2009, the patriarch announced that he would not unveil the Ark after all, but that instead he could attest to its current status.
Southern Africa
The Lemba people of South Africa and Zimbabwe have claimed that their ancestors carried the Ark south, calling it the ngoma lungundu or “voice of God”, eventually hiding it in a deep cave in the Dumghe mountains, their spiritual home.
On 14 April 2008, in a UK Channel 4 documentary, Tudor Parfitt, taking a literalist approach to the Biblical story, described his research into this claim. He says that the object described by the Lemba has attributes similar to the Ark. It was of similar size, was carried on poles by priests, was not allowed to touch the ground, was revered as a voice of their God, and was used as a weapon of great power, sweeping enemies aside.
In his book The Lost Ark of the Covenant (2008), Parfitt also suggests that the Ark was taken to Arabia following the events depicted in the Second Book of Maccabees, and cites Arabic sources which maintain it was brought in distant times to Yemen. One Lemba clan, the Buba, which was supposed to have brought the Ark to Africa, have a genetic signature called the Cohen Modal Haplotype. This suggests a male Semitic link to the Levant. Lemba tradition maintains that the Ark spent some time in Sena in Yemen. Later, it was taken across the sea to East Africa and may have been taken inland at the time of the Great Zimbabwe civilization. According to their oral traditions, some time after the arrival of the Lemba with the Ark, it self-destructed. Using a core from the original, the Lemba priests constructed a new one. This replica was discovered in a cave by a Swedish German missionary named Harald von Sicard in the 1940s and eventually found its way to the Museum of Human Science in Harare.
Parfitt had this artifact radio-carbon dated to about 1350, which coincided with the sudden end of the Great Zimbabwe civilization.
Europe
Chartres Cathedral, France
French author Louis Charpentier claimed that the Ark was taken to Chartres Cathedral by the Knights Templar.
Rennes-le-Château, then to America
Several recent authors have theorised that the Ark was taken from Jerusalem to the village of Rennes-le-Château in Southern France. Karen Ralls has cited Freemason Patrick Byrne, who believes the Ark was moved from Rennes-le-Château at the outbreak of World War I to America.
Rome
The Ark of the Covenant was said to have been kept in the Basilica of St. John Lateran, surviving the pillages of Rome by Genseric and Alaric I but lost when the basilica burned.
United Kingdom
In 2003, author Graham Phillips hypothetically concluded that the Ark was taken to Mount Sinai in the Valley of Edom by the Maccabees. Phillips claims it remained there until the 1180s, when Ralph de Sudeley, the leader of the Templars found the Maccabean treasure at Jebel al-Madhbah, returned home to his estate at Herdewyke in Warwickshire, England taking the treasure with him.
Ireland
During the turn of the 20th century British Israelites carried out some excavations of the Hill of Tara in Ireland looking for the Ark of the Covenant – the Royal Society of Antiquaries of Ireland campaigned successfully to have them stopped before they destroyed the hill.
Egypt
Tutankhamun’s tomb

In 1922 in the Egyptian Valley of the Kings the tomb of Tutankhamun (KV62) was opened by Howard Carter and Lord Carnarvon. Among the artifacts was a processional ark, listed as Shrine 261, the Anubis Shrine. Almost immediately after publication of the photographs of this sensational archaeological find some claimed that the Anubis Shrine could be the Ark of the Covenant. John M. Lundquist, author of The Temple of Jerusalem: past, present, and future (2008), discounts this idea. The Anubis Shrine measures 95 centimetres (37 in) long, 37 centimetres (15 in) wide, 54.3 centimetres (21.4 in) high, in the shape of a pylon. The Biblical Ark of the Covenant is approximately 133 centimetres (52 in) long, 80 centimetres (31 in) wide, and 80 centimetres (31 in) high in the shape of a rectangular chest.
He points out that Shrine 261 is not strictly analogous to the Ark of the Covenant: it can only be said that the Anubis Shrine is “ark-like”, constructed of wood, gilded and gessoed, stored within a sacred tomb, “guarding” the treasury of the tomb (and not the primary focus of that environment), that it contains compartments within it that store and hold sacred objects, that it has a figure of Anubis on its lid, and that it was carried by two staves permanently inserted into rings at its base and borne by eight priests in the funerary procession to Tutankhamun’s tomb. Its value is the insight it provides to the ancient culture of Egypt.
