built in the 15th century. After its reconstruction in 1963, it became part of the exhibition of the Budapest History Museum. The first chapel in the castle was probably built in the 14th century during the reign of Louis I of Hungary. Eberhard Windecke claimed in his Chronicle that Charles II of Hungary was murdered in 1386 in a room from which the royal chapel could be seen. The chapel was again mentioned in the Chronicle of Lorenzo de Monaci, which was written around 1390. King Sigismund of Luxemburg thoroughly rebuilt the old Anjou castle during the first decades of the 15th century. He erected a Gothic church in place of the former chapel. The Anjou castle’s faAade was now facing towards the inner palace courtyard, and the long chancel was projecting from the eastern side of the palace. The chancel was built upon a lower church due to a lack of space on the narrow plateau. The church had a 21m long nave and an 11m long chancel. The flamboyant Royal Church of Buda Castle was similar to the more famous Sainte-Chapelle in Paris. Archeological research proved the date of the church, because 15th century strata were discovered under the intact brick floor of the lower church. In November 1489, Sultan Bayezid II of the Ottoman empire sent the relics of John the Almoner to King Matthias Corvinus. The King placed the relics in the Royal Chapel, which was re-dedicated and embellished with Renaissance furniture. In 1526, Buda was plundered by the Ottoman Turks after the Battle of MohA?cs. The relics were rescued in time and carried to Pressburg, where they are still kept. A surviving church inventory from 1530 shows a wealth of furnishings. Later, King JA?nos Szapolyai converted the lower church into a bastion. The large Gothic windows were walled up, and only the rectangular arrow slits were left open. In 1541 the Ottoman Turks captured Buda without resistance, and the Royal Church ceased to be a place of Christian worship. The upper church was destroyed in the 1686 siege of Buda, and the ruins were demolished in 1715. The vault of the lower church collapsed, and the interior was filled with rubbish. The remains were then buried under the new Baroque terrace for two centuries. The ruins of the lower church were discovered by archeologists in 1949A50. The remains were buried in 1953 because of conceptional disputes about the possible reconstruction. The chapel, finally reconstructed by 1963, was re-consecrated in 1990
