Site: The Adelphi (1 memorial)
WC2, Adelphi Terrace
The original Adelphi was a large development, even in modern terms. Most of the streets were named after the Adam brothers as was the whole Terrace since Adelphi is Greek for 'brothers'.
The four giant allegorical relief figures on the corners of the Embankment front are, listed west-east: 'Dawn' - Bainbridge Copnall; 'Contemplation' - Arthur J Ayres; 'Inspiration' - Gilbert Ledward; 'Night' - Donald Gilbert. Some other sculptural work is by Newbury Abbot Trent.
