Cave of Machpelah -  Sarah died in Hebron. Abraham bought the cave of Machpelah, as her burial place. Abraham was also buried there, as were his son and grandson, Isaac and Jacob.

Cave of Machpelah  Portion; double cave, the cave which Abraham bought, together with the field in which it stood, from Ephron the Hittite, for a family burying-place #Ge 23:1ff. It is one of those Bible localities about the identification of which there can be no doubt. It was on the slope of a hill on the east of Hebron, "before Mamre." Here were laid the bodies of Abraham and Sarah, Isaac and Rebekah, Jacob and Leah #Ge 23:19 25:9 49:31 50:13. Over the cave an ancient Christian church was erected, probably in the time of Justinian, the Roman emperor. This church has been converted into a Muslim mosque. The whole is surrounded by the el-Haram i.e., "the sacred enclosure," about 200 feet long, 115 broad, and of an average height of about 50 This building, from the immense size of some of its stones, and the manner in which they are fitted together, is supposed by some to have been erected in the days of David or of Solomon, while others ascribe it to the time of Herod. It is looked upon as the most ancient and finest relic of Jewish architecture. On the floor of the mosque are erected six large cenotaphs as monuments to the dead who are buried in the cave beneath. Between the cenotaphs of Isaac and Rebekah there is a circular opening in the floor into the cavern below, the cave of Machpelah. Here it may be that the body of Jacob, which was embalmed in Egypt, is still preserved (much older embalmed bodies have recently been found in the cave of Deir el-Bahari in Egypt,)  though those of the others there buried may have long ago mouldered into dust. The interior of the mosque was visited by the Prince of Wales in 1862 by a special favour of the Muslim authorities. An interesting account of this visit is given in Dean Stanley’s Lectures on the Jewish Church. It was also visited in 1866 by the Marquis of Bute, and in 1869 by the late Emperor (Frederick) of Germany, then the Crown Prince of Prussia. In 1881 it was visited by the two sons of the Prince of Wales, accompanied by Sir C. Wilson and others. (See Palestine Quarterly Statement, October 1882

Genesis 23:9 so he will sell me the cave of Machpelah, which belongs to him and is at the end of his field. Ask him to sell it to me for the full price as a burial site among you." Genesis 23:17 So Ephron’s field in Machpelah near Mamre— both the field and the cave in it, and all the trees within the borders of the field— was deeded Genesis 23:19 Afterward Abraham buried his wife Sarah in the cave in the field of Machpelah near Mamre (which is at Hebron) in the land of Canaan. Genesis 25:9 His sons Isaac and Ishmael buried him in the cave of Machpelah near Mamre, in the field of Ephron son of Zohar the Hittite, Genesis 49:30 the cave in the field of Machpelah, near Mamre in Canaan, which Abraham bought as a burial place from Ephron the Hittite, along with the field.
