Conservation repairs have been carried out to this Bastion, which forms part of the remains of the City Wall. The work was necessary in order to protect the Scheduled Monument from decay.

Moss and plant growth together with their root systems was removed. Decayed cement based mortar pointing was removed, followed by its replacement with lime mortar.

Loose stonework and brickwork was rebedded in lime mortar. Defective mortar caps to walls were replaced with lime mortar caps. Exposed areas were protected with lime mortar to allow water to run off. Eroded stonework was conserved and given shelter coats for protection and all loose flintwork was rebedded in lime mortar. Reigate stone surrounds to medieval arrow slits were conserved and shelter coated. Loose brick fill was removed to allow the openings to be more clearly seen.

Corroded ironwork was removed and replaced with stainless steel supports and cracks in masonry restrained with stainless steel rods while unstable masonry was cross stitched with stainless steel ties to sound masonry. A new stainless steel arch was installed to support the eroded brick arch.

The heap of loose masonry in the centre of the Bastion keep was sorted and all unrelated concrete, bricks and stones were removed.

In due course permanent fencing will replace the temporary chestnut



palings, which in the interim is protecting the archaeology on the south west corner.

The Bastion forms part of the City of London's Forts group and is considered to be medieval construction over the remains of the Roman Wall. The interior of The Bastion was lined with brickwork during the 19th Century when it was used as a warehouse. Following the destruction of the warehouse during bombing, the Bastion was identified as an historic structure, which saved it from demolition. The Bastion was the subject of an archaeological investigation in 1949 and subsequent research has confirmed its age.
