Preah Khan was built on the site of Jayavarman VII's victory over the invading Chams in 1181. Unusually the modern name, meaning "holy sword", is derived from the meaning of the original — Nagara Jayasri (holy city of victory).[1] The site may previously have been occupied by the royal palaces of Yasovarman II and Tribhuvanadityavarman.[2] The temple's foundation stela has provided considerable information about the history and administration of the site: the main image, of the boddhisatva Avalokitesvara in the form of the king's father, was dedicated in 1191 (the king's mother had earlier been commemorated in the same way at Ta Prohm). 430 other deities also had shrines on the site, each of which received an allotment of food, clothing, perfume and even mosquito nets;[3] the temple's wealth included gold, silver, gems, 112,300 pearls and a cow with gilded horns.[4] The institution combined the roles of city, temple and Buddhist university: there were 97,840 attendants and servants, including 1000 dancers[5] and 1000 teachers.[6] The temple is still largely unrestored: the initial clearing was from 1927 to 1932, and partial anastylosis was carried out in 1939. Since then free-standing statues have been removed for safe-keeping, and there has been further consolidation and restoration work. Throughout, the conservators have attempted to balance restoration and maintenance of the wild condition in which the temple was discovered: one of them, Maurice Glaize, wrote that;

 

Prasat Ta Som located in the east of Nean Pean. Entry and exit to Ta Som can only be access from east entrance. It was built in the end of the 12th century dedicated to the father of the king (Buddhist), replica to Bayon style of art.

Ta Som has not been restored. It is a small quiet temple and affords a delightful visit. In the past one of the significant features of Ta Som was the growth of fig trees the faces at the entrance towers. These have been cut from the east tower but they are still visible at the west one.

Ta Som is a single tower monument on one level surrounded by three enclosing walls with entry on the east and west carved with four faces, the face on the right of the east tower (1) (facing the temple) has a beautiful smile. The entry towers are in the shape of a cross with a small room on each side connecting to a laterite wall.
Walk through the first entry tower over a causeway, which crosses a moat and is bordered with serpents and large Garudas. The wall of the second enclosure is in laterite (2) with a sandstone entry tower in the shape of a cross on the east and west sides (3). The entry towers have windows with balusters on the exterior and proceeded by a porch with pillars.

The next enclosure comprises a laterite and sandstone gallery with corner pavilions (4), which have molded false doors. Amongst the crumbled heaps of stones in the courtyard are two libraries (5) opening to the west.

The main tower (6) is in the shape of a cross with four porches. To see the Central Sanctuary, courtyard and libraries, climb through the opening on the north side.

Banteay Srei (or Banteay Srey) is one of the most unusual temples of Angkor, Cambodia. It lies 20 km due north of the main group, at 13.59 N, 103.96667 E. It is built largely of red sandstone, which is covered with elaborate and deeply carved decoration.

Consecrated in 967, Banteay Srei was the only major temple at Angkor not built for the king; instead it was constructed by one of king Rajendravarman's counsellors, Yajnyavahara. The temple was primarily dedicated to Shiva the southern buildings and the central tower were devoted to him, but the northern ones to Vishnu. It lies near the hill of Phnom Dei 25 km (15 miles) northeast of the main group of temples, where the capital of the time (Yashodharapura) was located. The temple was subject to further expansion and rebuilding work in the eleventh century. At some point it came under the control of the king and had its original dedication changed; an inscription of the early twelfth century records the temple being given to the priest Divarakapandita and being rededicated to Shiva. It remained in use at least until the fourteenth century

The temple's original name was Tribhuvanamahesvara — great lord of the threefold world — named as usual after the central image (in this case a Shaivite linga. The town of Isvarapura was centred on the temple. The modern name, Banteay Srei — citadel of the women, or citadel of beauty — is generally taken to refer to the intricacy of the carving and the tiny dimensions of the architecture

The temple was rediscovered only in 1914, and was the subject of a celebrated case of art theft when André Malraux stole four devatas in 1923 (he was soon arrested and the figures returned). The incident stimulated interest in the site, which was cleared the following year, and in the 1930s Banteay Srei was restored in the first important use of anastylosis at Angkor. Until the discovery of the foundation stela in 1936, it had been assumed that the extreme decoration indicated a later date than was in fact the case. To prevent the site from water damage, the joint Cambodian-Swiss Banteay Srei Conservation Project installed a drainage system between 2000 and 2003. Measures were also taken to prevent damage to the temples walls being caused by nearby trees

The citadel of the cells . In the ruin and confusion of Banteay Kdei the carvings take one's interest. They are piquant, exquisite, not too frequent... they seem meant.. to make adorable a human habitation. Banteay Kdei is located south of Ta Prohm. A enter the monument from the west and leave at the west or vice versa, either way, also visit Srah Srang. It was built in middle of the 12th century to the beginning of the 13th century by king Jayavarman II in Mahaya Buddhism with following at least two different art periods Angkor Wat and Bayon  -are discernible at Banteay Kdei. 

Banteay Kdei has not been restored and allows the visitor to experience what it may have looked like originally. Changes and additions account for is unbalanced layout. Banteay Kdei was built of soft sandstone and many of the galleries and porches have collapsed. The wall enclosing the temple was built of reused stones.

The temple is built on the ground level use as a Buddhist monastery. The elements of the original design of Banteay Kdei seem to have been a Central Sanctuary (5), a surrounding gallery (6) and a passageway connected to another gallery. A moat enclosed the original features of the temple. Another enclosure and two libraries were among the additions in the Bayon period. The outer enclosure (700 by 500 meters 2,297 by 1,640feet) is made of laterite (1) and has four entry towers

A rectangular courtyard to the east is known as 'the hall of the dancing girls', a name derived from the decoration which includes dancers. The entry tower of the second enclosure is in the shape of a cross with three passages; the two on either end are connected to the literate wall of the enclosure 320 by 200 scrolls of figures and large female divinities in niches. In the interior court there is a frieze of Buddha.

A work of great dignity and impeccable proportions', wrote Mauize of Prerup in his guidebook of 1963.
Pre Rup is located at northeast of Srah Srang and 500 meters (1,640 feet) south of the south end of the East Baray. An entrance and exit  the monument from the east entrance. To climb to the upper terrace use the east stairway; it is slightly less steep than the others.

Tip: Because the temple is built entirely of brick and laterite, the warm tones of these materials are best are seen early in the morning or when the sun is setting. There are two views from the top terrace: the first looking east towards Phnom Bok and the mountain chain of Phnom Kulen; and the second looking west where the towers of Angkor Wat can be distinguished on the far horizon. 
It was built in second half of the tenth century (961) by the King Rajendraman II dedicated to the god Siva (Hindi), replica to Pre Rup style of art.

The boldness of the architectural design of Pre Rup is superb and give the temple fine balance, scale and proportion. The temple is almost identical in style to the East Mebon, although it was built several yeas later. It is the last real 'temple-mountain ' Pre Rup was called the  'City of the East ' by Philippe Stern, a Frenchman who worked on the site.
The Cambodians have always regarded this temple as having funerary associations but reason is unknown. The name Prerup recalls one of the rituals of cremation in which the silhouette of the body of the deceased, outlined with its ashes, is successively represented according to different orientations, Some archaeologists believe that the large vat located at the base of the east stairway to the central area was used at cremations.

Pre Rup dominates the vast plain, which the East Baray irrigated. Contracted on an artificial mountain in laterite with brick towers, the plan is square and comprises two enclosures (1 and 2) with four entry towers each and a base with three narrow tiers (3) serving as a pedestal for five towers on the top platform one in each corner and one central (4). The outer enclosing wall is 127 by 116 meters (417 by 380 feet).

Inside the outer laterite-enclosing wall there are two groups of three towers, one on each side of the entrance (5); the towers of each group share a common base. The middle tower in each of the two groups dominates and is more developed than the others. It appears that the first tower on the right was never built or, if it was, its bricks were reused somewhere else. The most complete lintel is on the tower at the far left (south )on the east face showing in his avataras a man-lion.
The next enclosure, also made of laterite, has four small entry towers, one on each side (2) Long galleries surround the courtyard on the enterior. The walls of these galleries, which have sandstone porches, are built of laterite.

In the courtyard there are vestiges of long rest halls (6) probably used by pilgrims. They have sandstone pillars in the east and laterite walls and windows with balusters in the west. In the northeast corner there is a curious small square building (7) built of large blocks of laterite and open on all four sides. The inscription of the temple was found in gallery near this building.

The entrance to Tep Pranam is marked by a laterite causeway bordered by double boundary stones at the corners and a terrace in the shape of a cross. The sandstone walls of the base of the temple have a molded edging. Two lions precede the walls and there are serpent balustrades, which are of a later date. See map page 80.

The large Buddha seated on a lotus pedestal is in a molded base and coated in sandstone. The body of the Buddha has been reassembled from numerous stones.
