The Royal Arsenal Gatehouse or Beresford Gate stands solitary at the north end of the square, isolated from the Arsenal since the rerouting of the A206.
It was designed by Colonel John T. Jones in 1828.
The oldest parts are of plain yellow stock brick with some stone detailing.
The later additions are of red brick and feature three large windows on each side and a clock at the top of its south-facing gable.
The gate has three openings which are currently closed off by iron fences.
The gatehouse is flanked by two original pavilions, both adorned with recessed rectangular panels and surmounted by brass mortars.
An 1859 western annex features a bell tower.
Two cattle drinking troughs of the Metropolitan Drinking Fountain and Cattle Trough Association from the 1890s and two modern stone benches have been placed on the south side of the gatehouse.

The row of buildings at what was once called the High Pavement are modern (Newman, Levinson & Partners, 1969–70), except for a modest late-19th-century survivor in the middle (nr.
5; Chessum & Sons, 1892–93).
The public lavatories, underground since 1913, were rebuilt above-ground in the early 1990s.
In front of the plain brick building stands another cattle drinking trough, this one from 1904.
