Its story
What it looks like
A cast-iron street bollard stands beside a narrow lane, its base ringed by a heavy chain that disappears into a slotted stone socket.
The bollard is polished where hands might steady themselves, but its lower half is scarred with fresh-looking dents.
Why it is here
To stop, trip, and briefly restrain people moving quickly through a narrow street.
Who made it
An anonymous city foundry, later modified by a watch engineer who wanted a quiet way to stop fleeing suspects.
Lore
The design began as a foundry safety device for restraining runaway carts.
City authorities adapted it for alleys where mounted patrols could not turn around. Older units are often mistaken for ordinary bollards, and some have been illegally reactivated long after their official removal.
Where it is found
Urban streets, alleys, courtyards, and market lanes
