Culture Christianity has deep roots in the Western Isles, but owing mainly to the different allegiances of the clans in the past, the people in the northern islands (Lewis, Harris, North Uist) have historically been predominantly Presbyterian, and those of the southern islands (Benbecula, South Uist, Barra) predominantly Roman Catholic. At the time of the 2001 Census, 42% of the population identified themselves as being affiliated with the Church of Scotland, with 13% Roman Catholic and 28% with other Christian churches. Many of this last group belong to the Free Church of Scotland, known for its strict observance of the Sabbath. 11% stated that they had no religion. This made the Western Isles the Scottish council area with the smallest percentage of non-religious in the population. There are also small Episcopalian congregations in Lewis and Harris and the Outer Hebrides are part of the Diocese of Argyll and The Isles in both the Episcopalian and Catholic traditions. Gaelic music is popular in the islands and the Lewis and Harris Traditional Music Society plays an active role in promoting the genre. Fèis Bharraigh began in 1981 with the aim of developing the practice and study of the Gaelic language, literature, music, drama and culture on the islands of Barra and Vatersay. A two-week festival, it has inspired 43 other feisean throughout Scotland. The Lewis Pipe Band was founded in 1904 and the Lewis and Harris Piping Society in 1977. Outdoor activities including rugby, football, golf, shinty, fishing, riding, canoeing, athletics, and multi-sports are popular in the Western Isles. The Hebridean Challenge is an adventure race run in five daily stages, which takes place along the length of the islands and includes hill and road running, road and mountain biking, short sea swims and demanding sea kayaking sections. There are four main sports centres: Ionad Spors Leodhais in Stornoway, which has a 25 m swimming pool; Harris Sports Centre; Lionacleit Sports Centre on Benbecula; and Castlebay Sports Centre on Barra.
