Keble College was founded in 1870, making it one of the newer colleges in the University of Oxford. It is now one of the largest colleges with a total of about 600 undergraduate and graduate students.
The college was founded in memory of Rev John Keble (1792-1866), Anglican priest, poet, professor, and hymn-writer. Rev Keble's Assize Sermon entitled National Apostasy, delivered at Oxford on 14 July 1833, is regarded as the beginning of the renewal movement known as the Oxford Movement or the Tractarian Movement. In that sermon, preached at the University Church of St Mary the Virgin, Keble condemned the growth of liberalism in the Church of England and took the nation to task for turning away from God and ignoring the prophetic calling of the church. The sermon caused a sensation across Britain.
Between 1833 and 1841, Keble, John Henry Newman, Edward Bouverie Pusey, and others issued a series of 90 pamphlets called Tracts For The Times (hence Tractarian Movement), in which they presented their views on ecclesiology and theology. Tractarianism emphasised the importance of the ministry and the sacraments as God-given ordinances, and ultimately developed into Ritualism or Anglo-Catholicism, which has been highly influential in the Anglican Communion as well as other Christian traditions.

The College was designed by William Butterfield, a leading exponent of Victorian Gothic. Butterfield was raised in a Nonconformist family, but later became a convinced High-Church Anglican. He and other architects influenced by the Oxford Movement looked to medieval cathedrals for inspiration and designed churches full of colour as a celebration of God’s creation. This photo shows Keble College Chapel. Some see Keble College and Chapel as the high point of Butterfield’s architectural achievements.

This photo shows the chapel's high altar. The chapel walls are lined with colourful mosaics showing Old Testament prophets, scenes from the life of Christ, and patristic and medieval saints.

In the Side-Chapel is the original version of William Holman Hunt's The Light of the World, one of the most famous religious paintings of all time. Hunt (1827-1910), one of the founders of the pre-Raphaelite Brotherhood, completed it in 1853. It was donated to the College in 1879 on the understanding that it would hang in the Chapel. William Butterfield, as the chapel architect, opposed this, however, and so it was not placed in the Side-Chapel until 1890. Hunt was so insulted by the treatment of his painting that he painted a duplicate version, now hanging in St Paul's Cathedral, London.

I was a member of Keble College during my year at Oxford, 1986-87, when the university awarded me a Master of Studies (M.St.) in Theological Ethics. I studied political philosophy under the brilliant moral theologian Rev Dr Oliver O'Donovan.
John Keble's page at the Cyber Hymnal lists 72 hymns. More biographical information can be found here. Some of Rev Keble's writings, including National Apostasy and seven Tracts For The Times, are posted here. All of the tracts are posted here.
