In 1924, a bronze monument with a stone pedestal dedicated to the Czech writer Svatopluk Čech was placed in the eponymous park (which bore his name from 1903) in Vinohrady. The sculptor of the statue was Jan Štursa, working together with the architect Pavel Janák. At the beginning of the 1940s (apparently in 1942), the statue was removed and taken to a metal storage site in Maniny. During the war, a water reservoir was also built in the park, later used in the construction of a garden pool with fountains.

The bronze bust of writer Karolina Světlá (1830–1899) was created by the sculptor Gustav Zoula and placed on a granite plinth according to the design by the architect Josef Fanta. The monument was unveiled on the west side of Charles Square on 29 May 1910. A black marble plaque with a gilded inscription which read: KAROLINA / SVĚTLÁ / 24. II. 1830 – 7. IX. 1899. MONUMENT TO THE CELEBRATED WRITER / AND FOR GRATITUDE FOR THE MERITS OF THE GREAT CZECH WOMAN / DEDICATED THE YEAR OF MDCCCCX. Originally there were large bronze vases decorated with laurel leaves on the sides of the plinth.

Palacký Square and its surroundings on the eastern bridgehead of the Palacký Bridge was one of the most affected areas from the accidental bombing by the 8th US Air Force on 14 February 1945. In his pictures of Palacký Bridge, Josef Sudek indirectly captured the square as well. He focused on the surroundings of the square in the large set of photographs of the nearby monastery Na Slovanech, known as Emmaus. In one picture, however, he captured the square itself with the ruined apartment building on the corner of Gorazdova and Na Moráni Streets (Na Moráni 3, no. 360/II).
