Question: Which Pharaoh built a temple to the north east of the Sphinx 1000 years after it was built?
About the article "Great Sphinx of Giza", section "Mythology".

Candidate passages:
Colin Reader has proposed that the Sphinx was probably the focus of solar worship in the Early Dynastic Period, before the Giza Plateau became a necropolis in the Old Kingdom (c. 2686–2134 BC).
He ties this in with his conclusions that the Sphinx, the Sphinx temple, the Causeway and the Khafra mortuary temple are all part of a complex which predates Dynasty IV (c. 2613–2494 BC).
The lion has long been a symbol associated with the sun in ancient Near Eastern civilizations.
Images depicting the Egyptian king in the form of a lion smiting his enemies date as far back as the Early Dynastic Period.
In the New Kingdom, the Sphinx became more specifically associated with the god "Hor-em-akhet" (Hellenized: "Harmachis") or Horus at the Horizon, which represented the pharaoh in his role as the "Shesep-ankh" (English: "Living Image") of the god Atum.
Pharaoh Amenhotep II (1427–1401 or 1397 BC) built a temple to the north east of the Sphinx nearly 1000 years after its construction, and dedicated it to the cult of "Hor-em-akhet".
During the New Kingdom, Giza was still an active site.
A brick-built chapel was erected near the Sphinx during the early 18th dynasty, probably by king Thutmose I. Amenhotep II built a temple dedicated to Hauron-Haremakhet near the Sphinx.
Pharaoh Thutmose IV visited the pyramids and the Sphinx as a prince and in a dream was told that clearing the sand from the Sphinx would be rewarded with kingship.
This event is recorded in the Dream stela.
During the early years of his reign, Thutmose IV together with his wife Queen Nefertari had stelae erected at Giza.
Pharaoh Tutankhamun had a structure built which is now referred to as the king's resthouse.
During the 19th dynasty, Seti I added to the temple of Hauron-Haremakhet, and his son Ramesses II erected a stela in the chapel before the Sphinx and usurped the resthouse of Tutankhamun. 
The largest and most famous sphinx is the Great Sphinx of Giza, situated at the Giza Plateau adjacent to the Great Pyramids of Giza on the west bank of the Nile River and facing due east ().
The sphinx is located in the north and below the pyramids.
Although the date of its construction is uncertain, the head of the Great Sphinx now is believed to be that of the pharaoh Khafra.
What names their builders gave to these statues is not known.
At the Great Sphinx site, the inscription on a stele by Thutmose IV in 1400 BCE, lists the names of three aspects of the local sun deity of that period, "Khepera–Rê–Atum".
The inclusion of these figures in tomb and temple complexes quickly became traditional and many pharaohs had their heads carved atop the guardian statues for their tombs to show their close relationship with the powerful solar deity, Sekhmet, a lioness.
Other famous Egyptian sphinxes include one bearing the head of the pharaoh Hatshepsut, with her likeness carved in granite, which is now in the Metropolitan Museum of Art in New York, and the alabaster sphinx of Memphis, Memphis, Egypt, currently located within the open-air museum at that site.
The theme was expanded to form great avenues of guardian sphinxes lining the approaches to tombs and temples as well as serving as details atop the posts of flights of stairs to very grand complexes.
Nine hundred with ram heads, representing Amon, were built in Thebes, where his cult was strongest.
Perhaps the first sphinx in Egypt was one depicting Queen Hetepheres II, of the fourth dynasty that lasted from 2723 to 2563 BC.
She was one of the longest-lived members of the royal family of that dynasty.
The Great Sphinx has become an emblem of Egypt, frequently appearing on its stamps, coins, and official documents. 
Despite conflicting evidence and viewpoints over the years, the view held by modern Egyptology at large remains that the Great Sphinx was built in approximately 2500 BC for the pharaoh Khafra, the builder of the Second Pyramid at Giza.
Selim Hassan, writing in 1949 on recent excavations of the Sphinx enclosure, summed up the problem:"Taking all things into consideration, it seems that we must give the credit of erecting this, the world's most wonderful statue, to Khafre, but always with this reservation: that there is not one single contemporary inscription which connects the Sphinx with Khafre; so, sound as it may appear, we must treat the evidence as circumstantial, until such time as a lucky turn of the spade of the excavator will reveal to the world a definite reference to the erection of the Sphinx.
"The "circumstantial" evidence mentioned by Hassan includes the Sphinx's location in the context of the funerary complex surrounding the Second Pyramid, which is traditionally connected with Khafra.
Apart from the Causeway, the Pyramid and the Sphinx, the complex also includes the Sphinx Temple and the Valley Temple, both of which display the same architectural style, with 200-tonne stone blocks quarried out of the Sphinx enclosure.
A diorite statue of Khafre, which was discovered buried upside down along with other debris in the Valley Temple, is claimed as support for the Khafra theory.
The Dream Stele, erected much later by the pharaoh Thutmose IV (1401–1391 or 1397–1388 BC), associates the Sphinx with Khafra.
When the stele was discovered, its lines of text were already damaged and incomplete, and only referred to "Khaf", not Khafra.
An extract was translated:"... which we bring for him: oxen ... and all the young vegetables; and we shall give praise to "Wenofer" ... "Khaf" ... the statue made for "Atum-Hor-em-Akhet"."
The Egyptologist Thomas Young, finding the "Khaf" hieroglyphs in a damaged cartouche used to surround a royal name, inserted the glyph "ra" to complete Khafra's name.
When the Stele was re-excavated in 1925, the lines of text referring to "Khaf" flaked off and were destroyed. 
The temples of Khafre's complex survive in much better condition than Khufu's, this being specially true to the Valley Temple, which is substantially preserved.
To the east of the Pyramid sits the mortuary temple.
Though it is now largely in ruins, enough of it survives to understand the plan.
It is larger than previous temples and is the first to include all five standard elements of later mortuary temples: an entrance hall, a columned court, five niches for statues of the pharaoh, five storage chambers, and an inner sanctuary.
There were over 52 life size statues of Khafre, but these were removed and recycled, possibly by Rameses II.
The temple was built of megalithic blocks (the largest is an estimated 400 tonnes).
A causeway runs to the valley temple.
The valley temple is very similar to the mortuary temple.
It is built of megalithic blocks sheathed in red granite.
The square pillars of the T shaped hallway were made of solid granite and the floor was paved in alabaster.
The exterior was built of huge blocks some weighing over 100 tonnes.
Though devoid of any internal decoration, this temple would have been filled with symbolism: two doors open into a vestibule and a large pillared hall, there are sockets in the floor that would have fixed 23 statues of Khafre, these have since been plundered).
The interior made of granite of the Valley temple is remarkably well preserved.
The exterior made of limestone is much more weathered.
The so-called temple of the Sphinx is not attested to any king, but structural similarities to Khafre's mortuary temple point to him as its builder.
Opening to a hall with 24 columns, each with its own statue, two sanctuaries and symmetric design, it is possible but unsure if this temple had any symbolism attached to the finished plan.
