What is Bristol Threatened History Society?

Bristol Threatened History Society (BTHS) is a registered charity which supports archaeological activity in the City of Bristol.

It provides advice to archaeologists working in the city and helps to provide funds to facilitate their work and to inform the public about the city's past.


What is the Importance of Bristol?

Bristol is acknowledged as one of the foremost historic cities in Europe. It was the country's second city for much of the medieval period and was a major port and manufacturing centre. It had trading links with much of Europe and latterly with the New World, as well as with Ireland, Wales and the West Country.

Outside the central core, there are important sites from the prehistoric period onwards, including extensive prehistoric and Roman landscapes on the Severnside levels around Avonmouth, an Iron Age hillfort at Blaise Castle, an important Roman villa at Kingsweston, a Roman town at Sea Mills and medieval and post-medieval farms still surviving.

What is the threat?

Bristol has a long and distinguished history of archaeological research stretching back to the 19th century and beyond. With new planning regulations now in force, archaeology is now regularly taken into consideration in all new development projects.

However, it is not always possible to safeguard the city's heritage in the face of sometimes overwhelming development pressures. Support is needed to back up those arguing the case for conservation.

We need now to take stock of the work which has already been carried out and to devise new programmes of research to enable a better understanding of Bristol's development.
