The photograph in the OP is by R. J. C. Atkinson, January 1958 and its caption is:
STONEHENGE, Wiltshire. Re-erection of Trilithon lintel 158 by the 60 ton 'Brabazon Crane', the larger of two cranes used to lift stones. The lintel is being lowered and man-handled into its final resting position on upright stones 57 and 58
While Stonehenge definitely existed before 1954, with photographs going back to the 1867, it has not been simply left to the forces of nature over the past couple centuries, but instead has been subjected to further human activity such as stabilization and restoration efforts.

STONEHENGE WORLD HERITAGE SITE
‘RESTORING’ STONEHENGE 1881-1939 for historical photographs and an explanations of modern changes to the site in that period of time and later.
Numerous references, such as Stonehenge by Malone and Barnard confirm that:
In 1958 a 60-ton mobile crane was used to restore the stones that had fallen in 1797 and 1900
And according to the New Scientist article Concrete evidence:
virtually every stone was re-erected, straightened or embedded in concrete between 1901 and 1964...
...The first restoration project took place in 1901. A leaning stone was straightened and set in concrete, to prevent it falling.
More drastic renovations were carried out in the 1920s. Under the direction of Colonel William Hawley, a member of the Stonehenge Society, six stones were moved and re-erected.
Cranes were used to reposition three more stones in 1958. One giant fallen lintel, or cross stone, was replaced. Then in 1964, four stones were repositioned to prevent them falling.
The 1920s ‘restoration’ was the most “vigorous”, says Christopher Chippindale of the Cambridge University Museum of Archaeology and Anthropology. “The work in the 1920s under Colonel William Crawley is a sad story,”
For early descriptions of Stonehenge, see the 1740 Stonehenge: A Temple Restor'd to the British Druids and the 1747 Choir Gaure, Vulgarly Called Stonehenge, on Salisbury Plain. Unfortunately Google Books omits many of the drawings in these books, but the 1747 is considered the earliest quantitatively accurate description.
Between pages 32 and 33 of the 1740 book, there is a drawing of Stonehenge dated August 1722, showing that it was reasonably similar then as now.
