The Architecture of Thailand is a major part of the country's rich cultural legacy and reflects both the challenges of living in Thailand's sometimes extreme climate as well as, historically, the importance of architecture to the Thai people's sense of community and religious beliefs. Influenced by the architectural traditions of many of Thailand's neighbors, it has also developed significant regional variation within its vernacular and religious buildings
A prang is a tall finger-like spire, usually richly carved. This was a common feature of Khmer religious architecture and was later adopted by Thai builders, typically in the Ayutthaya (1350–1767) and Bangkok periods. In Thailand it appears only with the most important religious buildings.
The first Prangs in Thailand were built e.g. in Phimai and Khao Phnom Rung and Lopburi between the early 10th century and the late 12th century, when the Khmer kingdom was dominant. They influenced the old Khmer architect, who also built great temple complexes such as Angkor Wat and Angkor Thom
A "more modern" Prang is a slim construction, like an ear of corn, which lets its Khmer origin be only suspected.
in the history, many people, countries and empires they tried very hard to bring back the Thai knowledge and treasures.
The Franco-Siamese War of 1893 was a conflict between the French Third Republic and the Kingdom of Siam. Auguste Pavie, French vice consul in Luang Prabang in 1886, was the chief agent in furthering French interests in Laos. His intrigues, which took advantage of Siamese weakness in the region and periodic invasions by Vietnamese rebels from Tonkin, increased tensions between Bangkok and Paris. Following the conflict, the Siamese agreed to cede Laos to France, an act that led to the significant expansion of French Indochina.

Named after its designer, engineer Gustave Eiffel, the Eiffel Tower is the tallest building in Paris.

Since then the mention of Siam has inspired visions of a lush Far Eastern paradise...a land of of great Kings and Queens, gilded palaces, complex culture and intricate handicrafts. The truth about Siam is every bit as exotic as the fantastic accounts Westerners have related for 400 years.
Today, the essence of Siam lives in the hearts and minds of sixty million Thai citizens and millions of enamored visitors alike. It is embodied in the living culture of Thailand.
