Boomhall Gate Pillars, Near 33 Culmore Road, Londonderry

These are the gate pillars and associated segmental walls of what was once a grand entrance, now surrounded by suburban housing and in a derelict state. Dating from approximately 1760 to 1779, the pillars and walls formed the former main entrance to Boom Hall (listed separately as HB01/25/004A). They appear on an 1830 map, alongside a gate house to the south-east. It is likely that the pillars were designed by Michael Priestly, the architect for Boom Hall.

The structure consists of four pillars: two originally marked the entrance gates, and two define the ends of the segmental walls. The pillars are faced with ashlar sandstone. The walling is of whinstone, topped with a sandstone coping. The northernmost pillar is the best preserved and stands 2.5 metres to the underside of the coping, measuring 1.1 metres across at its base and the same depth. A recessed area, 200mm by 800mm and rising 2 metres, is present on the south side of this pillar, displaying the remnants of wrought iron fixings for the former gates. This recess is rendered with lime mortar, revealing brickwork behind. The coping is finely cut with a projecting cornice, although it is missing from the sister pillar to the south. The end walls are 1.5 metres high, while the end pillars themselves are 2 metres high, both retaining their coping which matches that described above. A concrete bollard has been placed centrally to discourage vehicle access.
