Sacred Heart Cathedral, Brazzaville: seat of a cardinal abducted and murdered in a 1977 coup

On the Butte de l’Aiglon, in Brazzaville, the cathedral of the Sacred Heart was built between 1892 and 1894 under the direction of the Spiritan missionary bishop Prosper-Philippe Augouard, with seven to eight hundred thousand bricks made locally, and consecrated on 3 May 1894. The two towers were added in 1904, and the bell tower was rebuilt in concrete in 1952, work attributed, though with less certainty, to the architect Roger Erell. It is commonly called the oldest cathedral still standing in central Africa. The Catholic jurisdiction in the French Congo was erected as an apostolic vicariate on 4 June 1886, renamed the apostolic vicariate of Brazzaville in 1922 and raised to a metropolitan archdiocese on 14 September 1955. Among its archbishops is Cardinal Émile Biayenda, in office from 1971, abducted from his residence beside the cathedral on 22 March 1977, during the coup that cost the life of the Marxist president Marien Ngouabi and of the former president Alphonse Massamba-Débat. He was killed by his abductors, who were never identified. He is buried in this cathedral, and his cause of canonisation was opened in 1995. During the period of single-party Marxist government set up by Colonel Denis Sassou-Nguesso from 1979, the Catholic schools were nationalised and the Church faced restrictions on its public role, although no direct damage to the cathedral building during the Congolese civil wars of the Nineties is documented. The present archbishop is Bienvenu Manamika Bafouakouahou, installed on 21 November 2021. Pope John Paul II visited this cathedral on 5 May 1980, meeting the clergy during a one-day stop in Brazzaville, on a journey that also took in Zaire, Kenya, Ghana, Upper Volta and Ivory Coast. Diplomatic relations between the Holy See and the Republic of the Congo go back to February 1963.

History

Consecrated in 1894 and widely cited as central Africa’s oldest standing cathedral, Sacred Heart Cathedral’s darkest chapter came in March 1977, when its archbishop, Cardinal Émile Biayenda, was abducted from his residence next to the cathedral and murdered during the coup that killed Marxist president Marien Ngouabi — a crime whose perpetrators were never identified. He is buried in the cathedral he once led, and his cause for sainthood opened in 1995. The building survived decades of one-party Marxist rule, during which Catholic schools were nationalized nationwide, and later received a visit from Pope John Paul II in 1980, though no source confirms whether it suffered direct damage during the country’s devastating 1990s civil wars.
