Museum Siam, housed in the former Ministry of Commerce building, is a striking example of early 20th-century Western classical architecture in Bangkok. Originally completed in 1922, the building reflects the modernisation of Siam through both its design and its role in international trade administration.
King Prajadhipok (King Rama VII) (1893–1941) was the seventh monarch of the Chakri dynasty, reigning from 26 November 1925 until his abdication on 2 March 1935. His nine-year reign was marked by significant political, social, and cultural changes, as Siam navigated the global economic depression and transitioned towards constitutional monarchy.
Mario Tamagno (1877 – 1941) was an Italian architect who served under contract in Siam’s Department of Public Works, overseeing the design of major Western-style buildings during the late reign of King Rama V and King Rama VI.
Ming Muang Market, designed by Italian architect Mario Tamagno and opened in 1932, was a modern textile market in late King Vajiravudh’s reign. Inspired by Middle Eastern-style clothing bazaars, it served as a hub for fast, quality tailoring in Bangkok. Today, the site has transformed into “The Old Siam Plaza,” blending nostalgic atmosphere with modern commerce.
A senior nobleman of Siam during the 19th century, Chaophraya Mahinthrasakthamrong (1821–1894) was a pioneer of modern Thai theatre, introducing Western theatrical forms and aesthetics to Bangkok and creating the innovative Lakhon Phanthang (“hybrid theatre”) style.
The Prince Theatre, built during the reign of King Rama IV, was the first theatre in Bangkok influenced by Western architecture and performance styles. Founded by Chaophraya Mahinthrasakdithamrong, it combined traditional Thai lakhon nok with Western elements, creating a novel genre known as Lakhon Phanthang.
The Bangkok tram system operated from 1888 to 1968, making Thailand the second country in the region to adopt trams for public transport. Initially horse-drawn, it was later electrified, transforming the city’s mobility and urban landscape.
Henry Alabaster (1836–1884) played an important role in introducing Western knowledge and technology to Siam. He contributed significantly to the development of public works, transportation, communication, education, and public parks. Saranrom Park is one example of his vision for public spaces to support civic and cultural development alongside the country’s modernisation.

Western-style policing began in Siam during King Rama IV’s reign, known at the time as pontrawen (patrol officers). The Phra Ratchawang Metropolitan Police Station, originally located near Tha Tian Market, was later relocated to its current site. The building was designed by Italian architect Mario Tamagno, who also designed the Ministry of Commerce building behind it. In fact, the police station was completed around seven years before the Ministry building.

His notable works include the layout of the Memorial Bridge and the design of the King Rama I Monument.
Captain Samuel Joseph Bird Ames played a key role in establishing the first Western-style police force in Bangkok in 1860. This initiative came at a time when European powers were expanding in Asia, and domestic law enforcement was seen as essential to national defence and diplomacy.
Sala Chalermkrung Royal Theatre is a historic theatre on Charoen Krung Road in Bangkok. It was built to celebrate the 150th anniversary of the city during the reign of King Prajadhipok (Rama VII). It was the first cinema in Thailand with air conditioning and a modern design. Today, it is still in use as a venue for classical dance, theatre, and special film events.
Charoen Krung was Bangkok’s first modern road, constructed between 1861–1864 during the reign of King Mongkut (Rama IV). Designed by Henry Alabaster, it stretched over 8.5 km along the eastern bank of the Chao Phraya River, marking a shift from canal-based to road-based urban development.
Tha Tien Market, nestled opposite Wat Pho and close to the Grand Palace, has long been one of Bangkok’s oldest riverfront trading hubs. It began as a busy dockside market in the Ayutthaya, Thonburi, and early Rattanakosin periods. In the 20th century, it changed into a planned market with European-style shophouses. Later, the area changed again. The market moved away from wholesale trade and became a place for culture and tourism instead.
The Siam Electricity Company was founded in 1898, with its power plant located on the grounds of Wat Ratchaburana Ratchaworawihan (commonly known as Wat Liab). This steam-powered plant burned wood, coal, oil and rice husks as fuel and became known as the “Wat Liab Power Plant.” It brought electric light to the Phra Nakhon and Thonburi areas, providing power for streets, royal palaces, and key public buildings.
Poh-Chang Academy of Arts was founded in 1913 during the reign of King Vajiravudh (King Rama VI), building upon the foundations laid earlier by the “Wood Carving Division” and the “Craftsmen’s Guild” established under King Chulalongkorn (King Rama V). Conceived as a means to preserve traditional Thai craftsmanship while embracing modern knowledge, the school played a pivotal role in shaping modern Thai art. It brought together Thai artisans and pioneering foreign instructors such as Frederick Samuel Harrop, who introduced Western artistic techniques, and Prince Chudadhut Dharadilok, the first commandant who established its formal curriculum and structure. Today, Poh-Chang is part of Rajamangala University of Technology Rattanakosin and remains a symbol of artistic training where Thai cultural heritage and international approaches continue to converge.
Rajini School, founded in 1904 by Queen Saovabha Phongsri, was one of the first schools in Thailand to provide formal education for girls. Established to give Thai women the opportunity to learn, develop skills and build good character, it has played a leading role in shaping education for women in modern Thailand.
Suankularb Wittayalai School, founded during the reign of King Chulalongkorn (King Rama V), was the first royal school in Thailand. It was established as part of the King’s vision to modernise the country through education, ensuring that young people, nobles, officials, and citizens gained the knowledge and discipline needed to serve the nation in a changing world.
Originally a royal private garden, Saranrom Park evolved over time into a botanical garden, a zoo, and a venue for social and political activities. It reflects Siam’s transition from a traditional kingdom into a more open and modern Thai society.
The Memorial Bridge (Phra Phuttha Yodfa Bridge), commonly known as Saphan Phut, was the first bascule steel bridge in Bangkok. Opened in 1932 during the reign of King Prajadhipok (King Rama VII) to mark the 150th anniversary of Rattanakosin, it links the historic Phra Nakhon district on the east bank with Thonburi on the west bank. Beyond its function as a river crossing, the bridge symbolises the expansion of Bangkok across the Chao Phraya and the embrace of modern engineering that transformed the capital into a modern city in the early 20th century.
Replica of the Royal Clock Tower on Sanam Chai Road, built in 1982 to commemorate the 200th anniversary of Rattanakosin. It honours the original clock tower once located in the Grand Palace, a 19th century landmark of modernisation during the reign of King Mongkut (Rama IV).

King Chulalongkorn (1853–1910), the fifth monarch of the Chakri dynasty, reigned for 42 years during a period of intense pressure from colonial powers. His reign was marked by major reforms that transformed Siam into a modern state, aiming to ensure that the kingdom was recognised as civilised and independent by Western nations.
King Vajiravudh (1881–1925), the sixth monarch of the Chakri dynasty, ruled Siam during a period marked by both external and internal challenges. These included the First World War, economic difficulties, and continued reforms following the reign of his father, King Chulalongkorn. His reign is noted for significant contributions in administration, education, health, and the arts.
Queen Saovabha Phongsri (1854–1919), known as the Queen Mother of Thailand, played a pivotal role in pioneering women’s education in Siam. At a time when women had limited access to learning, she championed the idea that the nation’s progress depended on the education of both men and women. She promoted women’s intellectual and moral development, supporting education in languages, science, mathematics, and ethics.
