The excerpt below is from The Golden Legend.
...he ascended from the mount of Olives by Bethany; the which mountain, by another relation, is said the mountain of three lights. For by night on the side of the west it is lighted of the fire that burneth in the Temple, which never is put out ne quenched. On the morning it is light of the orient, for she hath first the rays of the sun before it shineth in the city, and also it hath great abundance of oil that nourisheth the light, and therefore it is said the hill of three lights. Unto this hill Jesu Christ commanded his disciples that they should go. For on the day of his Ascension he appeared two times, one time to eleven disciples that ate in the hall where they had supped with him. All the apostles and the disciples and also the women, abode in that part of Jerusalem which is called Mello, in the mountain of Sion, where David had made his palace. And there was the great hall arrayed and ordained for to sup, whereas Jesu Christ commanded that they should make ready for to eat the Paschal Lamb, and in this place the eleven apostles abode, and the other disciples, and the women abode in divers mansions there about. And when they had eaten in this hall, our Lord appeared to them and reproved them of their incredulity. And when he had eaten with them, and had commanded them that they should go to the Mount of Olivet on the side by Bethany, he appeared again to them, and answered to them of the demands that they made to him indiscreetly, and with his hands lifted he blessed them; and anon before them he ascended unto heaven. Of the place of this ascension saith Sulpicius, Bishop of Jerusalem, and it is in the gloss. For there was edified a church in the place where were made the signs of his ascension. Never sith might be set there any pavement, it could not be laid ne set but anon it issued out, and the stones of the marble sprang into the visages of them that set it. And that is a sign that they be stones on which Christ passed upon, which lie in the powder and dust, and abide for a token and sign certain.
The church mentioned in the above excerpt is known as the Chapel of the Ascension, built c.390. Muslims seized control of it in 1198 and added the dome.
The signs of His Ascension, as mentioned in The Golden Legend, are Christ's footprints in stone.
