The 2.75-acre (11,000 m2) mausoleum was designed by architect
Theodore Heuck. By 1862, the Royal Tomb at Pohukaina was full and there were no space for the coffins of
Prince Albert, who died August 27, 1862, and King
Kamehameha IV, who died November 30, 1863. Kamehameha IV's funeral was delayed for three months while a new mausoleum was built.
Robert Crichton Wyllie, Minister of Foreign Affairs, was buried here in October 1865. Over time, the remains of almost all of Hawaii's monarchs, their consorts, and various princes and princesses would rest at the Royal Mausoleum.
Kamehameha I and
William Charles Lunalilo are the only two kings not resting at the mausoleum. Lunalilo, the shortest-reigning Hawaiian monarch (one year and 25 days only), was buried in the
Lunalilo Tomb in the church cemetery in the courtyard of
Kawaiahaʻo Church.
Princess Nāhiʻenaʻena and
Queen Keōpūolani are buried on
Maui at
Waiola Church. Kamehameha I's remains were hidden in a traditional practice to preserve the
mana (power) of the aliʻi at the time of the
Hawaiian religion.
Additional modifications On November 9, 1887, after the main mausoleum building became too crowded, the caskets belonging to members of the Kamehameha Dynasty were moved to the newly built Kamehameha Tomb, an underground vault commissioned by
Charles Reed Bishop, husband of
Bernice Pauahi Bishop. The Territory of Hawaii built a second underground crypt, the Wyllie Tomb (formerly known as the Queen Emma Tomb) in 1904 to separate the caskets of Robert Crichton Wyllie and the relatives of Queen Emma. In 1907, the Territory of Hawaii allocated $20,000 for the construction of a separate underground vault for the Kalākaua family. Queen Liliʻuokalani and Prince
Jonah Kūhiō Kalanianaʻole were consulted in the construction process. On June 24, 1910, the caskets from the Kalākaua family were moved to newly constructed Kalākaua Crypt in a torchlit nighttime ceremony supervised by the former queen. In 1922 the main building was converted to a chapel after the last royal remains were moved to tombs constructed on the grounds. The chapel was added to the
National Register of Historic Places on August 7, 1972. == Legal status ==
