Book nowOverview
The IESF British section presents an evening lecture by Sue Threader, one of two elected bridgemasters of London.
The role of Bridgemaster originated in 1176 to oversee the construction of Old London Bridge and the management of its properties, accounts and ceremonies.
Over the centuries, the office and responsibilities evolved, but the position was often marred by financial fraud, election manipulation and negligence.
In this lecture, Sue will provide a fascinating insight into one of the oldest appointments in civic society and bridge engineering.
She will share stories of scandal and controversy, while also exploring the modern role of the Bridgemasters in supporting and promoting the charitable work of the City Bridge Foundation.
