The Burial Ground is Grade I listed and the extensive entry at the English Heritage website mentions the pillars (piers) in the "Boundaries" section:

"BOUNDARIES The burial ground is bounded by walls, railings and gates dating to 1868 (east side) and 1878 (west side), both separately listed. A listed brick wall to the south dates to the C18 or early C19 whilst the northern side of the burial ground is bounded by brick walls of 1964-5. The eastern boundary comprises a low coped wall of dressed stone between five granite piers, the piers square in plan and coped and gabled in a Greek Revival manner. The piers record the history of the burial ground and the names of some of the luminaries buried there, quoting verbatim an earlier inscription on C17 gate piers recorded by Strype in 1720. The railings have spearhead standards and finials and are gathered at intervals in clusters of eight. There are iron gates in second bay from the north. The western boundary, also separately listed, is a low brown brick wall in Flemish bond surmounted by fourteen square brick piers, capped with stone. Iron railings with bracketed supports are set in a plinth of cast-iron, with gates in the sixth bay from the north."
