The National Trust is excited to announce the start of vital conservation work on the iconic Mathematical Bridge at Wightwick Manor & Gardens. This historic bridge, admired by visitors for over a century, is set to undergo careful restoration, ensuring its structural integrity and historical authenticity are preserved for future generations.

A bridge rich in history and design

Built c.1900 and inspired by the original Mathematical Bridge at Queens' College, Cambridge, the Mathematical Bridge at Wightwick Manor and Gardens has long been a treasured feature of the estate. Both Theodore and Geoffrey Mander, former owners of Wightwick Manor, who studied at Queens' College, were instrumental in adding this unique structure to the grounds of their family home. Spanning Wightwick Bank and connecting the main gardens to a small woodland area, the bridge has captivated visitors with its elegant and geometrical design.

Although the bridge was rebuilt in 1949 to raise its centre for bus clearance and underwent strengthening in 1978 and 1992, it has been closed to the public since 2019 due to significant deterioration. Now, this much-anticipated conservation project aims to restore the bridge to its former glory, ensuring its continued presence as a highlight of Wightwick Manor & Gardens.

Conservation Project: What to Expect

The conservation work will begin at the end of October 2024 and is expected to be completed by early 2025. The project will involve specialists in historical preservation, working alongside the National Trust team to assess and repair the bridge’s timber structure. They will replace the deteriorated walkway and repair the handrail and supporting framework to maintain the bridge’s original character.

An architectural marvel

The bridge was built using straight wooden beams that form an arc, with other pieces connecting them to make the structure strong and stable. This construction, called 'tangent and radial trussing,' is both an efficient structural use of timber and a precise and elegant geometric design – hence the given name of ‘Mathematical Bridge’.

How will this work affect local residents and visitors?

To ensure the safety of motorists and contractors, Wightwick Bank will be temporarily closed to vehicular traffic during the conservation period, with diversions in place. Pedestrian access along Wightwick Bank will be maintained wherever possible. There should be minimal disruption to your visit whilst on site. The National Trust will provide regular updates on the progress of the project and is committed to minimising disruption wherever possible.

The National Trust extends its gratitude to all members, donors, and supporters whose contributions have made this essential work possible. Their generosity ensures that Wightwick Manor & Gardens continues to serve as a place of inspiration, history, and beauty for everyone to enjoy.
