Eilean na Moine Island, in the loch, was used as Dumbledore's grave.
The famous island used for Harry Potter in Loch Eilt is called Eilean na Moine. It was used as Dumbledore's grave, which was later digitally placed on Loch Arkaig.
After Dumbledore sadly dies in the movie, he is buried on a small island adorned with trees on Hogwarts Great Lake. What is this? His grave is also known as the White Tomb and it is the only grave located at Hogwarts. The Elder Wand was buried with him (before Voldemort stole it).
Following Voldemort's death on 2 May at the conclusion of the Battle of Hogwarts, Harry Potter, the one who had slain Voldemort utilising his mastership of the Elder Wand, returned the wand to the White Tomb, restoring it and ensuring Dumbledore's resting place would remain undisturbed.
When Voldemort came for the Elder Wand he broke the Tomb and took the Wand from Dumbledore. After the Hogwarts war and Voldemort was finally vanquished, Harry mentions that he will return the Elder wand to its rightful location, which is the Tomb of Dumbledore. We may assume that he fixed the tomb then.
Dumbledore had hoped, by having the Elder Wand placed with him in his tomb, that the power of the Wand would then be ended; the wand would transfer its allegiance to the latest person who had captured it, and as Snape had killed Dumbledore, it would be Snape to whom the wand owed its allegiance.
Voldemort then took the Elder Wand from Dumbledore's grave, but the wand never really obeyed him because it was Draco who disarmed Dumbledore in Harry Potter and the Half-Blood Prince.
Albus Dumbledore
"Severus, please." Watching Snape kill the Hogwarts headmaster was gutting; finding out that Dumbledore "begging for his life" was actually begging Snape to kill him was a sad reminder of just how selfless this man was.
In the novels and per the plan, Dumbledore is killed by Snape during the Battle of the Astronomy Tower. In the following days, a funeral is held for the Hogwarts headteacher down by the lake, attended by all students and teachers (excluding Snape).
“Of Course It Is Happening Inside Your Head Harry, But Why On Earth Should That Mean That It Is Not Real” The last words Dumbledore would speak to Harry were the same in the Harry Potter books and movies.
Following Lord Voldemort's defeat at the hands of her student Harry Potter and the deaths of Headmasters Albus Dumbledore and Severus Snape, McGonagall takes the position of Headmistress.
After some searching, Harry and Hermione find the ancient grave of one Ignotus Peverell, marked with the sign Grindelwald used, and the grave where Harry's father and mother are buried.
Fawkes left Hogwarts, possibly becoming a wild phoenix. Shortly before his departure, Fawkes conjured a flame which engulfed Dumbledore's body and reformed into the White Tomb. Fawkes is never heard from again, as Harry noted that he knew that the phoenix left Hogwarts forever.
The tomb was prepared by the teachers, not Dumbledore. They did not know his wand had any special value, so they would not have known to protect the tomb in any way.
In the sixth book, Dumbledore dies when facing Severus Snape on top of the Astronomy Tower, as Harry helplessly watches from concealment.
July 1996: Albus Dumbledore destroys Marvolo Gaunt's ring with Godric Gryffindor's sword in his headmaster's office at Hogwarts.
Snape tells Harry that he, Snape, is the Half-Blood Prince, and that Harry should not use his own spells on him, as Harry's father did. Harry dares Snape to kill him and calls him a coward once more.

Snape's last words imply his urgent desire to get a glimpse of Lily Potter's eyes, a woman he had loved his entire life and for whose death he felt largely responsible. Harry is constantly reminded throughout the series that he has his mother's eyes.
Warner Bros. Harry kills Voldemort during the Battle of Hogwarts, and the villain's last sounds are a scream of pain as he dies. In the book, his last line is "Avada Kedavra," which he casts at Harry before it rebounds and kills him instead.
“Dumbledore didn't want to lose his wand at that point and Draco disarmed him. So that meant that the wand gave Draco its allegiance, even though Draco never knew it, even though Draco never touched it. “From that moment on, that wand gave its allegiance to Draco, and it wouldn't work as well for anyone but Draco.”
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
We know the Elder Wand allied with Draco Malfoy, who disarmed rather than killed Albus Dumbledore. It later switched its loyalty to Harry Potter during his escape from Malfoy Manor. While deaths did occur in both situations (Dumbledore and Dobby respectively), neither Draco nor Harry committed the act.
