Temple plans
Kakatiya shrines are classified by the number of sanctuaries they enclose: ekakuta (one), dwikuta (two), trikuta (three), chatuskuta (four) and panchakuta (five). The Thousand Pillar Temple faces south.

The Ramappa complex from the air. The main temple's platform, with its many projecting corners, sits within a rectangular walled enclosure.

1 · Ekakuta
An ekakuta has one shrine with a pillared hall in front of it. The Ramappa Temple has one shrine and three entrances to its hall.
3 · Trikuta
A trikuta has three shrines on three sides of one pillared hall. At the Thousand Pillar Temple, Shiva is on the west, Vishnu on the north and Surya on the east, and the temple faces south.

5 · Panchakuta
Erukala Nancharigudi at Ramanujapur began as a trikuta. Builders later added two shrines on the east and west and joined them to a second hall. The source does not give the position of the second hall, so the drawing places it schematically.

The drawings are schematic plans seen from above. They show how the parts are arranged, not their measurements.
Sand-box foundations
The Ramappa Temple stands on a sand-box foundation. The builders dug a pit two to three metres deep and filled it with sand. They built a dry-stone retaining wall one to two metres high round the pit and filled it with sand. A second wall, 1.5 metres high, raised the bed further. The sand reached a total depth of about six metres. The nomination dossier says that this confined bed of sand spreads the load of the temple.

The sand box also has a weakness. Engineers from the Regional Engineering College, Warangal, found that the sandstone floor beams resting on the sand had broken. The four main dolerite pillars of the hall have settled as a result.

Materials

Inside the mandapa: a pillar of polished black stone, turned into rings and carved with friezes of small sculptures, beside a carved shrine doorway.
Dolerite is the signature material of Kakatiya sculpture. At Ramappa it was used for pillars, door jambs, lintels and the bracket sculptures. The 1900 survey noted at Uparpalle that this fine-grained black stone allows the very finest chiselling, takes a high polish, and is very uniform in colour and grain.

At Ramappa the four main load-bearing pillars of the hall are of dolerite. Granite was used for other columns and beams that carry heavy loads. The body of the temple is pink Chelvai sandstone, which gives it a pinkish colour.

The Ramappa vimana is built of brick light and porous enough to float on water. The dossier gives these bricks a density of 0.85 to 0.90 grams per cubic centimetre. Each brick measures about 14 by 6 by 4 inches and weighs about 3 kilograms. The 1900 survey recorded that the Palampet sikhara was built entirely of brick, moulded to suit the design, with a smaller temple to the north also carrying a brick sikhara.

The bracket sculptures
The madanikas are female bracket sculptures that project from the columns. The Ramappa dossier calls them the most described sculptures of the Kakatiya period. At Ramappa they spring from the shoulders of the dolerite columns to carry the overhanging cornice. The 1900 survey called the sculptured brackets “a marked feature” of the temple.

Not all the brackets are madanikas. These show rearing lion-like vyalas over small elephants, in dark stone on sandstone column capitals.

The sculptors gave each sculpture a different role, such as dancer, huntress, drummer or a woman garlanding herself. The dossier counts 38 bracket sculptures on the hall, and twelve of them are madanikas. Elsewhere the same dossier gives 40 madanikas and gaja-vyalas, each about six feet tall.

The doors carry Gajalakshmi on their lintels. At Ghanpur, the antarala doorway of the main temple carries Siva Tandava.

Rulers and their feudatory chiefs endowed tanks to temples. The endowment inscriptions record the villages granted along with each tank.

Forts and walls

Tradition describes Warangal Fort as two works: an outer mud fort called Bhumikota and an inner stone fort called Kalukota. A wide, deep moat called Parikha encircled the mud rampart. The Kakatiya-period Kridabhiramamu calls that rampart Prakara. The sources disagree about the name Kanchu-kota, 'the bronze fort'. Parabrahma Sastry gives that name to the stone fort itself. M. Rama Rao gives it to a brick enclosure inside the fort, around the royal palace.

The sources record this as tradition, not as fact established by inscriptions.
The 1900 Archaeological Survey recorded two walls around the fort: an earthen wall and a stone wall. The survey found only four gateways, one each on the north, south, east and west. The survey reported that only the east and west gateways were then in use.
Sources: ASI 1900 · HRIDAY Warangal leaflet · Warangal District Gazetteer 1976
Later sources count eight gateways, four in each wall. Those sources give different numbers of bastions, from 46 to 77. This site uses the numbers of the 1900 survey, because that survey is earlier and more systematic.
The stone wall was built of rough, irregular blocks of black granite. The blocks were laid in layers, with flat and upright blocks in alternate layers. This arrangement balanced the great outward pressure on the wall. A heritage leaflet on Warangal describes this method.
