In 1349 Rudolf II married his daughter from his first marriage, Anna von der Pfalz, to King Charles IV, one of the most important rulers of the late Middle Ages.

Count Rudolf finally retired because of increasing illness, and handed the government business over to his brother and successor Ruprecht, who in 1356 was able to acquire the Electorate for the Palatinate.

Pfalzgraf Rudolf II decreed that the church of Saint Ägidius (Giles) in Neustadt should be converted into a memoria—a place of prayer and commemoration—for the Wittelsbachs, and wished to be buried there.

Her husband Rudolf II possessed a similarly ornate grave plate, which, however, has survived only badly damaged and is also located in the Catholic church section on the rear south wall, opposite to his wife.

Around 1910, city pastor Michael Glaser (1863-1915) erected four large statues of the Palatine rulers Rudolf II and Ruprecht I, and the women buried by their side Beatrix of Berg and Margaret of Sicily-Aragon.

They were created by the Munich sculptor Hubert Netzer from white Kelheim limestone and are located on the northern and southern nave wall of the Catholic part of the church.
