St Alphege (“Ælfheah”) was a Bishop of Winchester, later Archbishop of Canterbury. He was captured by Viking raiders in 1011 and killed by them the following year after refusing to allow himself to be ransomed. Alphege was canonised as a saint in 1078.
The church was built around then, according to Wikipedia: “The first church was built adjoining the London Wall, with the wall forming its northern side.The churchyard lay to the north of the wall.The earliest mention of this church dates to c. 1108–25, though it is said that it was established before 1068.”
The ruins of the Church have recently been made beautiful, and accessible, by the wonderful new public space around One London Wall Place. Here is is a sketch done from one of the wooden benches close to the church:

You see the marvellous new high walks, which curve in the sky.
Until I started drawing them, I had not realised that the walls of the highwalk vary in height. The highwalk is made of some material which rusts, to give this bright orange colour.
On the right of the picture is the red brick of the old London Wall. The building in the background is Roman House, on Wood Street, a residential block.
The architects of One London Wall are MAKE architects.
