London has many street bollards, some are from cannons said to be from the Napoleonic wars, others copied from the originals. But the only one as far as I'm aware of a policeman is the bollard on Gerald Road in Belgravia, it is a unique three-foot-tall iron street marker shaped like a traditional police officer. The iron bollard styled Bobby with a helmet and silver badge wearing a uniform. It stands outside the former Gerald Road Police Station, which operated from 1846 until it closed in 1993 and has since been converted into a luxury private residence, but the policeman bollard and the original police overhead lantern remain as a reminder to the building's history.

The Plessey electronics factory on Ley Street in the London Borough of Redbridge was a major local manufacturer, employer, and a vital wartime production site. Plessey established premises on Ley Street around 1924 after moving from earlier local sites, growing into one of the largest electronics and telecommunications employers in the area. The television pioneer John Logie Baird worked from a workshop on the roof of the Plessey premises on Ley Street during the 1920s. After heavy German bombing damaged surface facilities during the 1940 Blitz, Plessey moved a massive defense manufacturing operation into the uncompleted Central line tube tunnels between Leytonstone and Gants Hill. Up to 4,000 workers (predominantly women) worked 24-hour shifts in the deep tunnels producing vital war goods, including bomber wireless receivers, field telephones, wiring sets for Halifax and Lancaster bombers. The original Ley Street factory buildings have since been demolished and replaced by modern housing developments.

The Haunted Cellars of Millbank Prison. Beneath the Morpeth Arms, Millbank, holds the original underground holding cells and part of a tunnel system from the old prison. This tunnel was used to march convicts directly from Millbank Prison to the river steps, where they were deported by ship to penal colonies in Australia. Many prisoners died of disease or malnutrition in these grim vaults before their ships even arrived. The hauntings are traditionally linked to two specific spirits: a prisoner who tragically hanged himself in the cells to avoid deportation, and another who was fatally shot down by guards during a desperate escape attempt. Staff and visitors have long reported sudden drops in temperature, intense feelings of panic, and objects moving on their own. Poltergeist activity is common; bottles have launched themselves from behind the bar, and drinks have been knocked clean off tables. The phenomenon became so frequent that the pub installed a closed-circuit "Ghost Cam". Customers can watch a live feed of the haunted subterranean tunnels directly from the comfort of the bar. I was given a private tour by bar staff a few years ago for the Knowledgeoflondon.com website. Very eerie experience!

The Mysterious Green "Mini" Stink Pipe, located at the eastern end of Shepherd's Bush Green near the Uxbridge Rd. The pipe is an anomaly among typical London sewer vents. Unlike standard 6-to-8-metre-tall columns, this specific cast-iron pipe is unusually short. It is dark green, features decorative ridges, and is uniquely topped with a distinctive circle of crenellations (a crown-like top). Because it is so low to the ground, local historians and urban explorers often debate its exact ventilation purpose. Its short height is highly unusual for venting foul odours directly into pedestrian paths. It is heavily speculated to have originally ventilated long-lost subterranean Victorian public toilets that once sat nearby

Peek Frean's company was founded in 1857 by James Peek, a London tea merchant and George Hender Frean, a ship's biscuit maker. They initially set up production in a disused sugar refinery on Mill Street in Dockhead. While Peek and Frean started the company, its legendary success is widely attributed to John Carr, who joined the firm and introduced innovative, modern biscuit-making machinery and techniques. Needing more space to fuel their rapid growth, the company bought a site integrated with the London and Greenwich Railway arches, opening the newer, massive factory at Drummond Road in 1866. Growing up in Bermondsey I can well recall the delicious smell of custard all about this area. Sadly the factory closed in May 1989.
