This Grade II listed Palladian arch, now built into the boundary wall of the Bromley-by-Bow Centre, is one of the few surviving 18th-century elements from the former Northumberland House. The arch once formed part of the house’s north entrance, added during renovations by Daniel Garrett, possibly following designs by the renowned architect William Kent. Following the demolition of Northumberland House, the arch was relocated to Tudor House, and later preserved within the Bromley-by-Bow Recreation Ground.

Constructed from rusticated and heavily vermiculated limestone, the semi-circular arch features projecting stone plinths, a moulded impost band, and a distinctive carved grotesque head at the dropped keystone. A moulded string course supports the balustraded parapet and cornice. The arch is now integrated into a red brick boundary wall and includes modern metal gates.

London Stone Conservation was commissioned to restore the arch. The work involved surface cleaning, removal of sulphation, stonework repairs, and restoration of the lead flashing. The project was delivered in partnership with the Heritage of London Trust and formed part of one of the earliest initiatives under the Proud Places programme, engaging the local community in celebrating and preserving London’s historic fabric.
