A village shaped by centuries
Situated on the gentle slopes of the North Downs, Merstham is a quaint village with a rich history. From its ancient church and early railway engineering to wartime structures and new community spaces, the village offers quiet reminders of the people and industries that shaped it.
A brief history
Merstham’s roots can be traced back over a thousand years. With its name recorded in forms dating back to the 10th and 11th centuries, including the Domesday Book of 1086. Early spellings such as Mearsoetham and Merstan reflect its Old English origins, often interpreted as meaning “a settlement by the marsh”.
Over the centuries, Merstham has evolved from a small agricultural settlement into the suburban village it is today. One of the key moments in its development came during the Industrial Revolution, when the arrival of the railway station in the 19th century spurred growth and connected the area to the larger cities of London and Brighton.

Surrey Iron Railway & the mystery of the Merstham Sighting Tower

Surrey History Centre ref: CC1101/3/101/11
On Quality Street in Merstham, you can still find evidence of the Surrey Iron Railway, opened in 1805 and considered the world’s first public railway—used for freight long before passenger trains. The surviving track display is completely hidden in plain sight.
South of the village you can find the Merstham Tunnels, originally built for the London, Brighton and South Coast Railway in the 19th century.
Tucked away on a hill above the M23 is the Merstham Sighting Tower, often mistaken for a ventilation shaft but actually an early 19th‑century surveying tower built to align the Merstham–Redhill railway tunnel. It’s difficult to find and wonderfully atmospheric.
The tower was constructed before the tunnel so that observers in the top of the tower could survey both ends of the tunnel from this one place.
How to find it: Travel further along the A23 towards Croydon and turn right into the B2031 Shepherds Hill and cross over the M23 motorway. Immediately after the bridge take the signposted path on the left. Walk up the path over two stiles to the top of the hill. On the way you will notice two ventilation shafts from the railway tunnel between Merstham and Coulsdon South. At the top of the hill is the sighting tower.
