The district was established by King Chulalongkorn, who wanted to escape the confines of Rattanakosin Island. Vimanmek Palace was constructed in 1900 completely out of teak, and was used as a royal palace for a short time, but was abandoned in 1908. Reconstructed in 1992, it is now a major tourist attraction of the district. Chitralada Palace was built by King Vajiravudh (Rama VI), and was a residence of King Bhumibol Adulyadej. The large park around the palace was used by the King for agricultural research.
Other important buildings in the district include the Ananta Samakhom Throne Hall, which was another former residence of King Chulalongkorn, and was later used as the first parliament building. It was built 1907-1915 by the Italian architects Annibale Rigotti and Mario Tamagno.
Next to the building is the Suan Amporn Park, and across the street the Dusit Zoo. The vast space in front of Ananta Samakom Throne Hall is the Royal Plaza. At the middle of the plaza is the equestrian statue of King Chulalongkorn. Various events are held in Suan Amporn Park and Royal Plaza. Yearly events include commencements for many universities in Bangkok, and the Red Cross Fair which takes place for nine days from the end of March till the first week of April.
Important administrative offices such as Government House are also in Dusit. Wasukri Pier is the pier to board and store royal barges, which sail in Thailand's Royal Barge Procession. Near the pier is the National Library of Thailand.

Chan Kasem Palace was initially built for the crown prince by King Rama V, but was never used by King Rama VI and later became the office of the Ministry of Education. Suan Sunandha Palace was built for the queen, consorts, princes and princesses, but is now home to Suan Sunandha Rajabhat University.
