The museum was established in 1903 with money donated by the great national benefactor Andreas Syngros, designed by the French architect Tournaire and originally consisted of 2 wings. Between 1935 and 1936, an extension of the building was created, while in 1956 a warehouse was added.

In 1958, based on the design of the architect Patroklos Karantinos, the museum acquired 2 new halls, while at the same time the 3 existing rooms were re-formed. In 1999, the institution was last renovated by the Hellenic Ministry of Culture with Alexandros Tombazis as the architect in charge. In its current form, it is housed in a 2-story structure, has a total area of 2,270 m² and consists of 14 rooms full of archaeological finds of great historical importance. It further has 558 m² of storage space, a ceramic and metal maintenance workshop, and a mosaic restoration studio. There is also a canteen and a pamphlet shop in the museum.

The exhibition focuses on the history of the Delphi Museum and includes objects that cover all periods from prehistoric to late antiquity. The exhibits are divided into sections so that visitors can view and understand them better.
