There is no evidence from the biblical canon that indicates where the Ark of the Covenant could be. There is some speculation from the Apocryphal book of 2 Maccabees.
However, somewhat interestingly, there was a claim made by Ron Wyatt (now deceased) that the Ark rests under where Jesus of Nazareth was crucified. Wyatt was an amateur archaeologist who has made some important discoveries regarding the Red Sea, Mt Sinai, Mt Horeb, Noah’s Ark, and Sodom and Gomorrah.
According to Ron Wyatt, the blood of Jesus flowed down from the Cross of Calvary through the cracks in the rocks below and onto the Ark of the Covenant buried in a cave below. He conducted seasonal excavations during his holidays over a number of years and claimed that he actually sighted the Ark. Oddly enough, somewhat happenstance, after having sighted the Ark, there was some movement in the ground and the tunnel became blocked, his work permit was cancelled, and the expedition ceased.
The exact location is not known, but it is definitely close to the Temple Mount. There is some film of his expedition to excavate the Ark in Jerusalem available. But nothing that reveals evidence of the Ark’s existence, regardless of the following claim:
It was back on Jan. 6, 1982 when Ron Wyatt realized what he had found during the excavation of the Ark of the Covenant.
“I just went from stunned to more stunned I guess,” he described . “When I started making the excavation I wasn’t looking for the Ark of the Covenant. I had no idea or intent to be looking for the crucifixion site, so as I proceeded with the excavation and found this crucifixion site, it was a thrill and a happy set of circumstances, and I didn’t make the connection with the blood on the mercy seat until I actually saw it.”
The reality is what the Ark of the Covenant represented is available to be experienced by all who seek the truth today.
Did Jesus Christ rise from the dead?
If He did, then personal contact ought to be available to all who genuinely seek Him out—emphasis on genuine. Evidently, being God, Lord Jesus Christ has the capacity to discern between the thoughts and intentions of your innermost being. He knows whether you are a phony or not. You can deceive Him, even if you are an expert at deceiving yourself.
