Adrian Phillips, in the book The Warminster Trail, compiled for the Warminster Festival 1989, and published by Aris & Phillips Ltd., wrote:
Opposite [the former National School] [at Church Street] are the buildings of St. Boniface.
Four phases mark this impressive building.
The first was the small stone building to the right of the centre, which was built, so it is said, to block the view of John Wansey who lived in Byne House opposite.
The central Georgian section, designed by J. Glascodine of Bristol, was built in 1790 by the same Wansey family on the profits of cloth.
On the right hand end is the neo-Jacobean building erected in 1897 by James Erasmus Philipps, q.v., as a missionary college which became accommodation for the Department of Theology of Kings College, London. This was transferred to Canterbury in 1962.
Finally, the chapel on the far left, with the magnificent theological library underneath, was added in 1927, as the foundation stone on the street commemorates.
