Immaculate Conception Cathedral, Dili
Plans to build the cathedral began in 1984 with the Indonesian Government providing funding totalling about US$235,000. The cathedral, situated on a 10,000-square-meter plot, measures 1,800 square meters and can hold 2,000 people. Indonesian President Soeharto on November 2, 1988 officially inaugurated Dili's new Catholic cathedral, reportedly the largest in Southeast Asia. The ceremony was attended by Dili's apostolic administrator, Bishop Carlos Filipe Ximenes Belo.
In October 1989 it was blessed by Pope John Paul II.
The Cathedral played an important part in the country’s independence struggle, with leaders like the Noble Laureate Bishop Belo advising people to go into the country’s election with the spirit of humility of Jesus Christ.
On 1 March 2007 the country's new Apostolic Nuncio, Archbishop Leopoldo Girelli, celebrated Mass at the Cathedral and then visited camps for displaced people in and around the capital, and the Seminary of Our Lady of Fatima.
On April 27, 2002 around 2,000 people gathered at the Cathedral for the arrival from Portugal of a statue of Our Lady of Fatima, which is to go on tour for three weeks as part of the celebrations ahead of the country’s independence. Mary, Our Lady of Fatima is the Patroness of East Timor. Among those welcoming the statue were Bishop Carlos Filipe Ximenes Belo, Bishop Basilio do Nascimento and other religious representatives.
The two Catholic bishops of East Timor and the papal nuncio to the country have jointly urged people to end a prolonged spate of violence and pray for national reconciliation and peace, after Mass on March 4, 2007 at Immaculate Conception Cathedral.
Father Jose Maia was the parish priest of Immaculate Conception Cathedral in 2009.
