In addition, stone blocks inscribed with "Lest We Forget" are positioned at angles to the tower. There are also inscription panels on the sides of the monument. Narrow pilasters decorate the angles of the clock tower. Arches are present over a niche and doorway. The top of the clock tower features a parapet with balustrade. Iron railings surround the memorial, which is prominently sited between Broadway and Upminster Road in front of Saint Helen and Saint Giles, the parish church of Rainham.
