Walbrook (river)
The Walbrook was a small, historic river in London that once flowed through the City of London, providing water and supporting local trade. It originated from natural springs and traveled underground for much of its course before discharging into the Thames. Over centuries, urban development led to its channel being covered or built over, making it largely invisible today. Its presence influenced the layout of ancient Londinium, and archaeological finds along its path reveal the area's long history. While no longer visible above ground, the Walbrook played a significant role in London's early development and urban history.
