The Roman fort hiding beneath a village near Darlington

Most people driving through have no idea what is hidden beneath their feet.

Piercebridge, a settlement on the banks of the River Tees, sits directly on top of a Roman fort built around 260 AD.

The village green, the surrounding houses, and the streets in between are all built over the remains of a garrison that once housed hundreds of Roman soldiers guarding one of the most strategically vital river crossings in the entire empire.

The fort is free to enter, open all year round, and is the number one thing to do in Piercebridge according to TripAdvisor, rated four stars from more than 50 reviews.

The road to the ends of the earth

To understand why the Romans were here, you have to understand Dere Street, the great Roman road that ran from York north through Durham, past Hadrian’s Wall and all the way to Scotland.

It was the empire’s main supply route to its northernmost frontier, and the River Tees was one of the most significant obstacles in its path.

The Romans built not one but three bridges here over the course of their occupation, first in timber around 90 AD, then again after flooding, and finally a monumental stone structure in the third century that was one of the most impressive engineering works in Roman Britain.

The fort, known in Roman times as Morbium, was built to guard that crossing.

At its peak, it held a full garrison with a headquarters building, a commandant’s house, barracks, stables, a hospital, granaries, and a bath house.

Outside its walls, a civilian settlement of merchants, traders, and their families grew up around it.

The river still holds their secrets

In the early 1980s, two local divers began exploring the bed of the River Tees near the old bridge site.

What they found astonished archaeologists.

Over the following decades, they recovered more than 5,400 Roman objects from a patch of riverbed barely five metres square: 1,400 coins, thousands of items of personal jewellery, military equipment, medical instruments, votive miniatures, and fragments of pottery, all coated in a strange concretion that had fused them to the riverbed.

Many had been deliberately broken before being thrown in.

Researchers believe the deposit represents a place of ritual offering, with soldiers, merchants, and travellers casting their most prized possessions into the Tees as gifts to the gods in exchange for safe passage across the bridge.

The finds are now held at the Bowes Museum in Barnard Castle.

Time Team investigated the site in 2010, calling it one of the most complex and layered Roman landscapes they had ever encountered.

What you can see today

The excavated portion of the fort sits behind a row of farmhouses, accessed through a gap between two buildings on the village’s Green Street.

A brown Roman Fort sign marks the entrance, easy to miss but worth finding.

Inside you can walk around the exposed foundations of the east gate, the surrounding defensive ditches, and the outline of the fort’s internal layout.

Information boards explain the site’s history, and on a dry day the earthworks of the Roman civilian settlement beyond the fort walls are visible as crop marks in the field to the east.

A short walk across the modern bridge leads to the Roman bridge site, where the enormous southern stone abutment of the original crossing still stands in a field, stranded almost 90 metres from the current riverbank after the Tees shifted course over the centuries.

It is a genuinely eerie sight: a massive slab of Roman masonry, still perfectly upright, standing alone in a meadow.

The pub with a song in its walls

Piercebridge has one more curiosity.

The George Hotel, a coaching inn on the village green said to date back in parts to the 16th century, is where American songwriter Henry Clay Work is believed to have been inspired to write My Grandfather’s Clock in the 1870s after seeing a longcase clock that had stopped when its owner died.

The clock is still there, in the bar.

What visitors say

Reviews on TripAdvisor paint a consistent picture, with the site regularly surprising people who stumble across it.

One visitor said: “We stayed at the George Hotel and just by chance decided to go for a walk around the village and wandered into the Roman Fort.

“Great information on the different parts of the fort. What a lovely village as well.”

Another said: “There’s not a lot to see but you do get the impression of what would have stood there nearly 2,000 years ago.

“Fascinating to see how the River Tees has moved.”

While another from York said: “The fort foundations, situated behind the church in the centre of the village, have information boards that give some idea of the size of the place.

“We didn’t spend long at either place but it was very interesting if you are in the area.”
