year by the Archdiocese of Cologne. Richeza died on 21 March 1063 in Saalfeld. Heritage Richeza was buried in Cologne's church of St. Maria ad Gradus and not, as she had wished, in Brauweiler. This was prompted by Archbishop Anno II, who appealed to an oral agreement with Richeza. The Klotten estate donated her funeral arrangements to St. Maria ad Gradus, whose relationship with Richeza, Hermann II and Anno II is unclear. Possibly St. Maria ad Gradus was an unfinished work of Richeza's brother and completed by Anno II, who wanted to secure part of the Ezzonen patrimony in this way. The Brauweiler Abbey claimed the validity of the 1051 charter and demanded the remains of the Polish Queen. The dispute ended in 1090 when the then-current archbishop of Cologne, Hermann III, ruled in favor of the monastery of Brauweiler. However, Richeza's grave remained in St. Maria ad Gradus until 1816, when it was transferred to Cologne Cathedral. Her grave was placed in the chapel dedicated to St. John the Baptist in a classic wooden sarcophagus. Beside the coffin hang two medieval portraits of Richeza and Anno II that originate from the medieval grave in St. Maria ad Gradus. Her grave was opened multiple times after the transfer to Cologne Cathedral. The last opening was in 1959 and revealed her bones. According to witnesses, Richeza had a small and graceful stature. Her collarbone showed traces of a fracture. Richeza's relics were located in St. Nicholas church in Brauweiler and were moved to the Klotter parish church in 2002. Marriage and issue Richeza and Mieszko had two children: Richeza (b. 1013) - married Béla I of Hungary Casimir (b. 1016) - Duke of Poland Legacy The most important of Richeza's projects was the re-building of the Abbey of Brauweiler. Her parents had founded Brauweiler, but the original church was modestly furnished, which was incompatible with the dynasty's territorial objectives. After Otto's death, Richeza decided to make Brauweiler the center of Ezzonen memory. Since the original building didn't suit this purpose, Richeza built a new abbey, which remains in good condition. When the construction began a three-aisled pillared basilica was planned with projecting transept to the east apse across a crypt. The aisles were groined vaults with flat ceilings in the central nave. Inside, the nave had five , each of which was half as large as the square crossing. Throughout the
