The memorial, designed by Sir Edwin Lutyens, was unveiled in 1921 and is today a grade II listed building.

Hartburn's memorial is one of fifteen War Crosses by Lutyens, all sharing a broadly similar design.

The commission for Hartburn came from Mr and Mrs Straker of nearby Angerton Hall, the gardens of which Lutyens renovated with Gertrude Jekyll in 1904.

It was unveiled on 31 July 1921 by Colonel EPA Riddel, CMG, DSO, commander of the 149th (Northumberland) Brigade.

Typical of Lutyens' War Crosses, it has a long, tapering shaft with short arms moulded near the top, though it has uncommonly deep bevelled edges and sits on a deep two-tiered stone base, which itself sits on a small stone circle in the grass.
