The sagas tell that Sokki Þórisson, a wealthy farmer of the Brattahlíð area, launched the idea of a separate bishop for Greenland in the early 12th century and got the approval of the Norwegian King Sigurd I Magnusson 'the Crusader' (1103–1130). Most of the clergy came from Norway.
The diocese was first assigned to the ecclesiastical province of the German Metropolitan Archbishopric of Bremen. The diocese was subject to the Archdiocese of Lund (present-day Sweden) from 1126 to 1152. Arnaldur returned to Norway in 1150 and became bishop of Hamar (Norway) in 1152.
The third bishop was Jón Árnason (nicknamed Smyril). He took office in 1189. In 1202–1203 he went on a pilgrimage to Rome and met Pope Innocent III. He died in Garðar in 1209 and was buried there, most likely in the Northern Chapel of the cathedral.
The next bishop, Helgi, arrived in Greenland in 1212 and was bishop until his death in 1230.
In 1234, Nikulás was ordained. He arrived in Greenland in 1239. He died in 1242.
Ólafr was ordained in the same year, arriving in 1247.[6] He remained bishop until the mid-1280s. He was abroad from 1264 to 1280, thus hardly serving in his own diocese.
The next bishop was Þórdr, who stayed in Garðar from 1289 until his return to Norway in 1309.[6]
The next bishop was Árni, from 1315 to 1347. Due to poor communication between Greenland and Norway, it was assumed that he had died and a new bishop (Jón Skalli) was ordained in 1343. When it was discovered that bishop Árni was still alive, Skalli resigned and never went to Greenland.[6] Jon Skalli never visited Garðar.[6]
After Árni's death in 1347 there was a 19-year vacancy period. Norwegian cleric Ivar Bardsson served as principal during the interim period.[6]
Bishop Álfr was ordained in 1365 and served as the last effectively residential bishop of Garðar until 1378. When Björn Einarsson Jórsalafari landed in Greenland in 1385, he found the diocese being administered by a priest.[7]
The Greenland diocese disappeared in the 15th century, when ships from Norway stopped arriving.[8][9]

In 1996, the diocese was nominally restored as Latin titular bishopric of Gardar (Curiate Italian) / Garðar (Norsk bokmål Norwegian) / Garden(sis) (Latin adjective).
Currently, the previous settlement of Igaliku is situated on the same geographic location. The site has been the subject of archaeological investigations since the 1830s. The cathedral was the primary target of much of the archaeological work and was fully excavated in 1926 by Danish archaeologist Poul Nørlund [da] (1888–1951). Nørlund made several scientific studies in Greenland starting in 1921 and ending in 1932.[15]
Many Norse settlement ruins remain visible in Igaliku. The ruins mostly consist of the stone foundations of the walls in their original positions so that the extent of the settlement, both individual buildings and collectively, can be determined and understood. The main ruin is of the Garðar Cathedral, a cross-shaped church built of sandstone in the 12th century. The maximum length is 27 m, the width 16 m. Two large barns are on the site, able to have held up to 160 cows.
