The Monument to the Liberator Tsar features a 4.5-meter bronze statue of Alexander II on horseback, set on a polished black granite pedestal. The total height of the monument reaches 12 meters. The middle part of the monument is adorned with figures and a massive cornice in the Renaissance style, culminating in a sculpture of the Russian tsar. Around the middle of the pedestal is a circular bronze relief depicting people led by the goddess of victory, Nike. The relief showcases the faces of over 30 military leaders and statesmen, including Generals Mikhail Skobelev and Joseph Gurko, Count Nikolai Ignatiev, and Prince Nikolai Nikolaevich the Elder. Three smaller bronze reliefs illustrate significant events: the Battle of Stara Zagora, the signing of the peace treaty in San Stefano, and the convening of the Constituent Assembly. The front part of the monument is decorated with a bronze laurel wreath, gifted by Romanian King Carol I in memory of the fallen Romanian soldiers, and the inscription "To the Liberator Tsar / Grateful Bulgaria."

The idea of creating a monument to the Liberator Tsar was first proposed in December 1892 at the II Congress of the Corps. A decision was made to establish a committee to raise funds for the construction of the monument to Alexander II and to build a home for veterans of the April Uprising and the Russo-Turkish War. The committee was chaired by Stoyan Zaimov, with Prince Ferdinand serving as honorary chairman, who made the first contribution of 50,000 leva. Deputies of the 10th National Assembly donated 300,000 leva, while the remaining funds were collected by public organizations and through the sale of a special postage stamp featuring Alexander II.

From February 15 to 18, 1900, the committee meetings developed a competition program for the monument's creation, defining mandatory elements and materials for its construction, as well as a budget of 300,000 francs and a prize fund: 5,000 francs for first place and 4,000 francs for second to fifth places. The competition conditions were sent to art academies worldwide, generating significant interest. Ninety sculptors from 13 countries registered for the competition, including nine from Paris, three from Florence and Sofia, two from Zurich, Berlin, and Prague, and one each from Rome, Vienna, Budapest, Copenhagen, Lisbon, The Hague, Hanover, Turin, Baku, Tbilisi, and Smyrna.

From September 1 to 15, 1900, models of the monument were displayed in the royal arena for public viewing. On September 20, Prince Ferdinand officially opened the jury session, which included Prof. Antonin Mercié from France, Prof. Ettore Ferrari from Italy, Prof. Robert Bach from Russia, Bulgarian artists Ivan Murvichka, Anton Mitov, Petko Klisurov, architect Nikola Lazarov, engineer Stoymen Sarafov, Stoyan Zaimov, and diplomats.

The winner of the competition was Florentine sculptor Arnaldo Zocchi. Second to fifth places were taken by German Gerhard Eberlein, Frenchmen Antonin Larue and Gaston Malet, Czech Frantisek Rous, and Frenchman Eugen Bovery. Five other participants, including teachers from the School of Arts Zheko Spiridonov and Boris Schatz, received commendations. The first stone of the monument's foundation was laid on April 23, 1901, in the presence of Prince Ferdinand I. The construction of the monument was completed on September 15, 1903, and the official opening took place on August 30, 1907, in the presence of Ferdinand I with his sons Boris and Cyril, Grand Duke Vladimir Alexandrovich, son of Alexander II, his wife Maria Pavlovna and their son Andrei, Minister of Defense General Kaulbars, General Stoletov, Commander of St. Petersburg General Parensov, and Arnaldo Zocchi.
