Indo-Saracenic architecture (also known as Indo-Gothic, Mughal-Gothic, Neo-Mughal, or Hindoo style) was a revivalist architectural style mostly used by British architects in India in the later 19th century, especially in public and government buildings in the British Raj, and the palaces of rulers of the princely states. It drew stylistic and decorative elements from native Indo-Islamic architecture, especially Mughal architecture, which the British regarded as the classic Indian style, and, less often, from Hindu temple architecture. The basic layout and structure of the buildings tended to be close to that used in contemporary buildings in other revivalist styles, such as Gothic revival and Neo-Classical, with specific Indian features and decoration added. The style drew from western exposure to depictions of Indian buildings from about 1795, such as those by William Hodges and the Daniell duo (William Daniell and his uncle Thomas Daniell). The first Indo-Saracenic building is often said to be the Chepauk Palace, completed in 1768, in present-day Chennai (Madras), for the Nawab of Arcot. Bombay and Calcutta (as they then were), as the main centres of the Raj administration, saw many buildings constructed in the style, although Calcutta was also a bastion of European Neo-classical architecture fused with Indic architectural elements. Most major buildings are now classified under the Heritage buildings category as laid down by the Archaeological Survey of India (ASI), and protected. The style enjoyed a degree of popularity outside British India, where architects often mixed Islamic and European elements from various areas and periods with boldness, in the prevailing climate of eclecticism in architecture. Among other British colonies and protectorates in the region, it was adopted by architects and engineers in British Ceylon (present-day Sri Lanka) and the Federated Malay States (present-day Malaysia). The style was sometimes used, mostly for large houses, in the United Kingdom itself, for example at the royal Brighton Pavilion (1787–1823) and Sezincote House (1805) in Gloucestershire. The wider European version, also popular in the Americas, is Moorish Revival architecture, which tends to use specific South Asian features less, and instead those characteristic of the Arabic-speaking countries; Neo-Mudéjar is the equivalent style in Spain. In India there had been an earlier inversion of the style in Lucknow before the British takeover in 1856, where Indian architects rather "randomly grafted European stylistic elements, as details and motifs, on to a skeleton derived from the Indo-Islamic school". This is known as the "Nawabi
