The antiquity of architecture of Karnataka () also known as Kannada architecture can be traced to its southern Neolithic and early Iron Age, Having witnessed the architectural ideological and utilitarian transformation from shelter- ritual- religion. Here the nomenclature 'Architecture' is as old as c.2000 B.C.E. The upper or late Neolithic people in order to make their shelters by their own they constructed huts made of wattle and doab, that were buttressed by stone boulders, presumably having conical roof resting on the bamboo or wooden posts into red murram or paved granite chips as revealed in archaeological excavations in sites like Brhamagiri (Chitradurga district), Sanganakallu, Tekkalakota (Bellary district), Piklihal (Raichur district). Megaliths are the dominant archaeological evidence of the early Iron Age (c. 1500 B.C.E – 100 C.E unsettled date). There are more than 2000 early Iron Age burial sites on record, who laid the foundation for a high non-perishable architecture in the form of various distinct architectural styles of stone-built burials, which are ritualistic in its character. The active religious architecture is evident 345 with that of the Kadamba Dynasty. Karnataka is a state in the southern part of India originally known as the State of Mysore. Over the centuries, architectural monuments within the region displayed a diversity of influences, often relaying much about the artistic trends of the rulers of twelve different dynasties.

Its architecture ranges dramatically from majestic monolith, such as the Gomateshwara, to Hindu and Jain places of worship, ruins of ancient cities, mausoleums and palaces of different architectural hue. Mysore Kingdom (Wodeyar) rule has also given an architectural master structure in the St. Philomena's Church at Mysore (extolled by the King as a structure of divine compassion and the eager gratitude of men) which was completed in 1956, in addition to many Dravidian style architectural temples. Two of the monuments (Pattadakal and Hampi) are listed under the UNESCO World Heritage List of 22 cultural monuments in India. Styles of Indo-Saracenic, Renaissance, Corinthian, Hindu, Indo-Greek and Indo-British style palaces were built in Mysore, the city of palaces. Sikh architecture at Bidar (1512) and also in Bangalore in 1956 can also be cited as having an impact on the architectural composition of the state.

Apart from the ancient traditional Buddhist Viharas which existed in India since ancient times, since the Independence of India in 1947, Karnataka has experienced some marked architectural changes, notably by the influx of Tibetan refugees which arrived in the state between 1963 and 1997, bringing with them the traditional Tibetan art and architectural styles, reflected in the Buddhist monastery at Bylakuppe for instance. Vidhana Soudha (built in Bangalore in 1953) and the tallest temple at Murudeshwar are the witnesses to the Neo–Dravidian architectural influences which have evolved since independence. The chronology of the architecture of Karnataka is elaborated in the right-hand box.

Kadamba architecture

The Kadambas of Banavasi were the ancient royal dynasty of Karnataka from 345 to 525, and made a significant early contribution to the architectural heritage of Karnataka. Dr. G. M. Moraes opines that apart from using some unique features, the Kadambas incorporated a diversity of styles in their architecture (Kadamba architecture), derived from their predecessors and overlords, drawing upon the architectural tradition of the Satavahanas for instance. The Kadambas were the originators of the Karnataka architecture. The most prominent basic feature of their architecture is the Shikara (dome), called Kadamba Shikara. The Shikara is pyramid shaped and rises in steps without any decoration, with a stupika or kalasha at the top. Occasionally the pyramids had perforated screen windows. This style of Shikara was used several centuries later, having an influence on the Doddagaddavalli Hoysala Temple and the Mahakuta temples in Hampi. The Madhukeshwara (Lord Shiva) Temple in Banavasi was built by Kadambas, and has an intricately carved stone cot. Originally built by the Kadambas, it has undergone, over a period of a thousand years, many additions and renovations, from the Chalukyas to the rulers of Sonda. "Kadambotsava", an annual cultural festival is held here in the month of December.

Dravidian architecture

Various temples in the Jaina, Shaiva and Vishnu traditions were built under the Western Ganga Sovereign Dynasty, which was subordinate to Pallava from 350 to 550, under Chalukya overlordship until 753 and under Rashtrakuta overlordship until 1100. The construction of monuments such as Gomateshwara (982–983) in places such as Shravanabelagola, Kambadahalli and Talakadu by the Western Ganga kings reflect a tolerance to different faiths. Some Vaishnava temples were built by the Gangas, such as the Narayanaswami temples in Nanjangud, Sattur and Hangala, in the modern Mysore district.Kamat pp. 314–316

Gomateshwara Gomateshwara (983), situated in Shravanabelagola is a monolithic statue standing high above a hill (618 steps climb leads to this monolith), and is visible from a distance of and regarded as one of the largest monolithic statues in the world. The statue was built by the Ganga minister and commander Chavundaraya (940–989) in honour of Lord Bahubali. Carved from fine-grained white granite, the image stands on a lotus. It has no support up to the thighs and is tall with the face measuring . With the serene expression on the face of the image, its curled hair with graceful locks, its proportional anatomy, the monolith size, and the combination of its artistry and craftsmanship have led it to be called the mightiest achievement in sculptural art in medieval Karnataka.Kamat p. 51 It is the largest monolithic statue in the world.

Panchakuta basadi (Jain basadi)

This is one of the most elegant monuments built in Dravidian, Vesara and Nagara styles during the period between 900 and 1000. The temple, which is oriented to the north towards the Brahmadeva pillar, has five shrines (hence the name Panchakuta). Three shrines are connected to a mantapa by a vestibule and consist of the main shrine of tirthankara Adinatha flanked by Neminatha shrine to the east and Shanthinatha shrine containing a tall idol of the tirthankara to the west. The other two shrines, which are disconnected and lie to the north of the trikuta cluster (three shrines), are also dedicated to tirthankaras. These are two different monuments.

Talakad Talakad is a historical site along the banks of the Cauvery River near Mysore. This small town, with a strong history and a prolonged period of human settlement was a flourishing city during the Hoysala period (12th–13th century), and was also an important trade centre during the reign of Gangas (from the 6th century for about 400 years) and Cholas (close of 10th century) and the Hoysalas from 1116. Towards the early 15th century it came under the Vijayanagara rule, and remained with them until the end of the 16th century. There are about a dozen temples spread over a small area of , perhaps reflecting the rich art, culture, trade and human activities that once existed there. The town now looks abandoned, except during the time of pilgrimage held once every few years. The temples, whose deities are regularly worshipped, such as the Kirthinarayana Temple, are either uncovered frequently or are protected continuously from accumulation of sand. The sand is removed to uncover them for a specific worship and an important pilgrimage held every five to twelve years; the recent Panchalinga Darshana pilgrimage was held during December 2006.

Nanjangud Temple The temple, located at Nanjangud on the right bank of the Kabini River, was originally built in Dravidian style by the Ganga Dynasty rulers in the 9th century during their occupation of this region. It has undergone extensions during the reign of Cholas, Hoysalas, and Wodeyars from the 9th to 19th centuries. It is one of the biggest temples in Karnataka with an area of and with a Gopura (tower) of height, which has seven stories with seven gold plated Kalasas on top of the Gopura.

The uniqueness of the temple is that it has 66 idols of Shaiva saints called as Nayanmars and more than 100 Lingas (of different kinds and sizes) including the main deity of Shrikanteshwara (Nanjundeshwara) Linga. Next to the Devi deity, in a separate chamber stands the emarald/jade Linga (Pachche Linga in kannada) popularly referred to as Hakim Nanjundeswara; a title given by Tippu Sultan. It is inscribed in the temple history that on the priests' special prayers to the deity, eyesight of the royal elephant was restored, where after the Sultan had a linga made of jade along with an emerald necklace and donated it to the temple.

Badami Chalukya architecture

The architecture is of a temple building idiom that evolved in the time period of 5th to 8th centuries in the area of Malaprabha basin, in present-day Bagalkot district of Karnataka state, sometimes called the Vesara style and Chalukya style. The earliest temples dating back to around 450 in Aihole when the Badami Chalukyas were feudatories of the Kadambas of Banavasi are also reflected during this period. According to historians, the Badami Chalukya contribution to temple building matched their valour and their achievements in battle. Their style included two types of monuments, namely the rock cut halls (caves) or cave temple features and the surface structural monuments.

Cave temples Cave temple architecture is found in the Badami cave temples at Badami, the early Chalukya capital, carved out in the 6th century. There are four cave temples hewn from the sides of cliffs, three Hindu and one Jain, which contain carved architectural elements such as decorative pillars and brackets as well as finely carved sculpture and richly etched ceiling panels. Nearby are many small Buddhist cave shrines. The four caves are simple in style. The entrance is a simple verandah with stone columns and brackets -a distinctive feature of these caves-leading to a columned mandapa and then to the small square shrine (sanctum sanctorum) cut deep into the cave. The temple caves represent different religious sects. Among them, two are dedicated to Lord Vishnu, one to Lord Shiva and the fourth is a Jain temple. The first three are devoted to the Vedic faith and the fourth cave is the only Jain temple at Badami.

The cave temples architecture is a blend of North Indian Nagara style and South Indian Dravidian style. Each cave has a sanctum sanctorum, a mandapa, a verandah and pillars. The cave temples also bear carvings, sculptures, and murals

Dravidian and Rekhanagara style of architecture of Rashtrakutas The Rashtrakutas who ruled the Deccan from Manyakheta, Kalaburagi district, Karnataka in the period 753–973 created the Dravidian style and Rekhanagara style of architectural monuments. One of the richest traditions in Indian architecture took shape in the Deccan during this time and one writer calls it Karnataka Dravida style as opposed to traditional Dravida style. Pattadakal UNESCO World Heritage Site and the Navalinga temples are the structural types of the Rashtrakutas.

Pattadakal

A group of monuments at Pattadakal, a UNESCO World Heritage Site, is located in the Bagalkot district of Karnataka. The temples of this group are the finest structural temples of this period and these are the Jaina, Dolmen, Kadasiddheswara, Jambulingeswara, Galaganatha, Chandrashekhara, Sangameswara, Kasivisweswara, Mallikarjuna, Virupaksha and Papanatha Temples.
