Historically rivers have been a hub for human settlement and have long been a key part of local livelihoods, history, and culture, as well as playing a role today in providing services and leisure to people who live around them. All four of the earliest human civilisations were formed on great rivers: the Nile, Euphrates, Indus, and the Yellow rivers. Cities have traditionally sprung up at bridgeheads or where a river could be forded at any time of the year. A local example in Buckinghamshire is Thornborough Bridge.
Thornborough was an important place in Roman times, marking the crossroads of five major roads. This east to west river crossing is at least 1,200 years old and dates back to Roman times. This position on Padbury Brook was originally a Roman ford, made from limestone blocks held in place with wooden stakes. These were found during excavations in the 1970s.
There are two large burial mounds to the north of the bridge that date to around 200 AD, and when excavated in 1839 by the Duke of Buckingham, produced a wealth of treasures; bronze and gold ornaments, pottery and glass. A glass urn containing human remains also survived, indicating that the mounds resulted from a lavish funeral ceremony.
The bridge itself dates to 1400 AD and is the sole surviving medieval bridge in Buckinghamshire and the oldest bridge in the county. It is made of stone with six stone arches, the centre two accommodating the main flow of the river. These centre arches are more ornate with ribbed vaults and carved voussoirs. Both arches are divided into three bays over the channels by two hollow-chamfered ribs and have hoodmoulds to the south side. The four remaining arches, two on each side, are less ornate and intended for Spring flooding overflows. There are three cutwaters on the south side central piers which are carried up through the parapet as passing pedestrian places. The north side has one square passing place with an inscription tablet and shields carved onto the pier below.
The bridge straddles the parish boundaries of Thornborough and Buckingham. The parish boundary follows the line of Padbury Brook or The Twins, a tributary of the River Great Ouse. The parish division is marked by a boundary stone in the middle of the bridge. The stone bridge is around 30 metres (98 ft) long and 4 metres (13 ft) wide.
There is evidence of multiple repairs carried out over the centuries, extensively in 1661 with other late 19th and 20th century repairs. There are fragments of an inscription on the north side of the bridge mentioning the 1661 repairs:
The parapets show 20th century damage by modern vehicles struggling with such a narrow road width.

We have lost many of our older bridges to the ravages of time and the modern practice of culvertisation and urban development. A few of our older bridges, like Thornborough, remain though, and their beauty and pivotal role in our history is starting to be recognised.

Varied in architectural structure and practical use, this beautifully illustrated volume reveals bridges to be a cornerstone of Buckinghamshire history and culture.
