The Rotunda houses the famous Feszty Panorama, the "Arrival of the Hungarians", which was originally completed on May 13, 1894. The cyclorama measures 15 meters tall and 120 meters long, forming a panorama painting with a 38 meter diameter. It is one of only 16 cycloramas in existence worldwide, making the painting an exceptionally rare work of art. The painting depicts the beginning of the Hungarian Conquest of the Carpathian Basin, commemorating the event which took place over 1000 years prior to painting's first exhibition in 1894. The cyclorama depicts various scenes from this initial conquest, including the arrival of the Seven Chieftains of the Magyars, and the sacrifice of a white horse by the pagan high priest, or "Táltos". The cyclorama was painted by Árpád Feszty from 1892-94, with the help of many assistants and fellow artists. Notably, the landscape was painted in large part by László Mednyánszky, and equestrian battle scenes were painted with the help of Pál Vágó.
