The plot of land that the palace now sits on was originally a steelworks founded by Antonín Reissenzahn [cs], primarily manufacturing farm equipment.

The paintings, 20 large canvases depicting mythological historical events in Czech history were extremely popular in Czechoslovakia.

[7] After the Nazi occupation of Czechoslovakia, the grounds of the palace complex were used as an assembly point, from which Jews living in Prague were transported to concentration camps.

[8] After the end of World War II, the building continued to be used for trade shows from 1946 to 1951, focusing less on commercial interests, and more on political ties to the Allies and the USSR.

[11] In 1976, the decision was made to begin renovations faithful to the original design,[12] after campaigning by the architectural firm SIAL [cs].

[5] In April 1985, the artist Margita Titlová Ylovsky hosted a one-day art exhibition in the palace while it was still actively being rebuilt.

[14] The building is eight stories tall, and is primarily constructed from reinforced concrete, with long strips on plain glass on the exterior.

It seems to have widened his horizons, with Corbusier stating afterwards that "When I saw the Trade Fair Palace, I realize how I have to create great buildings, I, who have up till now built only a few pretty small houses on modest budgets."

The Czech avant-garde architect Karel Teige gave a much more positive review of the building, commending its practical design and incorporation of light.
