Saint Mary’s Cathedral Rubaga, commonly referred to as Rubaga Cathedral; is the parent cathedral of the Roman Catholic Archdiocese of Kampala; the oldest Roman Catholic diocese in Uganda. It is also the home church of Archbishop of Kampala.
It is located on Lubaga Hill, in Lubaga Division, in the western part of the city of Kampala, the capital of Uganda and the largest city in that East African country. Lubaga is approximately 3 kilometres (1.9 mi), by road, west of the central business district of Kampala. Its coordinates are:0°18’09.0″N, 32°33’08.0″E (Latitude:0.302500; Longitude:32.552222).
Kabaka Mutesa I Mukaabya Walugembe, the 30th Kabaka of Buganda, who reigned from 1856 until 1884, once maintained a palace on Lubaga Hill. So, when fire destroyed the palace, he abandoned the hill and relocated to Mengo Hill. In 1889, his son Mwanga II of Buganda, donated that land to the French Catholic missionaries (White Fathers). These were setting up the nascent Catholic church in the country, at that time. Then in 1914 the missionaries began constructing a modern one at Lubaga (Rubaga). Construction was finally completed in 1925 and it was consecrated on 31 December 1925.
