a long nave and a two-storey gallery. The richly decorated six-vaulted stucco ceiling is borne by pillars rising from the galleries. The pillars bear grisaille frescos of Biblical figures, painted in the 1690s. The galleries were decorated during the reign of Frederick III (1648–1670) as can be see from his arms. The Chapel's most significant artifact is the organ, built by Esajas Compenius in 1610. It was installed by Compenius himself shortly before his death in Hillerød in 1617. The oldest organ in Denmark, it has 1,001 wooden pipes. Its original manually driven blower has been preserved. The instrument is richly decorated with ebony, ivory and silver. The altarpiece and pulpit from the early 17th century are the work of the silversmith Jacob Mores from Hamburg. In the king's prayer chamber adjoining the Chapel, there is a small silver altar crafted by the goldsmith Matthäus Wallbaum from Augsburg in 1600. Great Hall The Great Hall (Riddersalen) is situated above the Chapel and also extends over the length of the west wing. It was destroyed by fire in 1859 but was almost fully restored thanks to architectural paintings made by Heinrich Hansen and F.C. Lund. The restoration work, completed in 1880, was carried out by Ferdinand Meldahl who made use of preserved segments of the ornate gilded ceiling. The large chandelier in the centre of the room is the work of Meldahl's pupil, Carl Brummer. The original tapestries depicting important events in the life of Christian IV were woven in Karel van Mander's workshop in Delft. The copies decorating the walls of the hall today were created from Mander's sketches. The Rose The room on the ground floor in the King's Wing known as the Rose was originally a dining room for the king and his courtiers. It was also destroyed by the fire in 1859, but was reconstructed from old paintings. The two series of six vaults rest on free-standing pillars. It is thought Mehldahl managed to reuse parts of the window decorations including the monograms of Christian IV and Queen Catherine. Audience Chamber Extending into the middle islet, the Audience Chamber also escaped damage from the fire in 1859. It was decorated by Christian V's master builder Lambert van Haven in the 1680s, combining the Renaissance style with Baroque. He had himself brought the paintings in adjoining Privy Passage (Conseilgangen) back from Italy. His work was completed in 1688,
