The cathedral bears the title 'Menbere Tsebaot', or 'Pure Altar'. The church compound is the burial place for those who fought against the Italian Occupation, or those who accompanied the Emperor into exile from 1936 to 1941. The Emperor Haile Selassie and his consort the Empress Menen Asfaw are buried in the north transept of the cathedral. Other members of the Imperial Family are buried in the crypt below the church. The High Altar of the cathedral is dedicated to 'Agaiste Alem Kidist Selassie'. The other two altars in the Holy of Holies on either side of the High Altar are dedicated to St. John the Baptist and to 'Kidane Meheret'. In the south transept of the cathedral is a recently added chapel of St. Michael, which houses the Tabot or Ark of St. Michael the Archangel, which was returned to Ethiopia in February 2002 after being discovered in Edinburgh. This relic was taken by British forces from the mountain citadel of Magdalla in 1868 during their campaign against Emperor Tewodros II.
Architecture
The cathedral complex also includes the 'Bale Wold' Church, which is also known as the Church of the Four Heavenly Creatures. This church served as the original Holy Trinity Monastery Church before the building of the Cathedral and dates back to the reign of Emperor Menelik II. Other facilities include a primary and a secondary school, a monastery and the Holy Trinity Theological College, a museum and monuments housing the remains of those massacred in Addis Ababa by the Italians in 1937 in response to an assassination attempt against the Fascist Viceroy of Italian East Africa. In addition is the monument and tomb of the officials of the imperial government who were executed by the CommunistDerg regime. Holy Trinity Cathedral is the official seat of the Orthodox Archdiocese of Addis Ababa. The Patriarchs of the Ethiopian Orthodox Tewahedo Church are enthroned at Holy Trinity Cathedral and all Bishops are consecrated there as well.
