===Stonehenge 2 (c. 2900 BC)===
The second phase of construction occurred approximately between 2900 and 2600 BC.<ref name="Burns">{{cite book |last1=Burns |first1=William E. |title=Science and Technology in World History |date=2020 |publisher=ABC-CLIO |page=100}}</ref> The number of postholes dating to the early third millennium BC suggests that some form of timber structure was built within the enclosure during this period. Further standing timbers were placed at the northeast entrance, and a parallel alignment of posts ran inwards from the southern entrance. The postholes are smaller than the Aubrey Holes, being only around {{convert|0.4|m|in|order=flip}} in diameter, and are much less regularly spaced. The bank was purposely reduced in height and the ditch continued to silt up. At least twenty-five of the Aubrey Holes are known to have contained later, intrusive, [[cremation]] burials dating to the two centuries after the monument's inception. It seems that whatever the holes' initial function, it changed to become a funerary one during Phase two. Thirty further cremations were placed in the enclosure's ditch and at other points within the monument, mostly in the eastern half. Stonehenge is therefore interpreted as functioning as an [[enclosed cremation cemetery]] at this time,<ref name="Burns"/> the earliest known cremation cemetery in the British Isles. Fragments of unburnt human bone have also been found in the ditch-fill. Dating evidence is provided by the late Neolithic [[grooved ware]] pottery that has been found in connection with the features from this phase.
