The National Trust is excited to announce the reopening of the Mathematical Bridge at Wightwick Manor & Gardens after extensive conservation work. This historic bridge, admired by visitors for over a century, is has undergone 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, following the completion of an extensive conservation project, the bridge has been fully restored to its former glory and reopened to visitors, once again on 22 January 2025, serving as a highlight of Wightwick Manor & Gardens.

Conservation Project: A job well done

The conservation work, which began in late October 2024 and was completed in January 2025, involved specialists in historical preservation working alongside the National Trust team to carefully assess and repair the bridge’s timber structure. The deteriorated walkway was replaced, and the handrail and supporting framework were meticulously repaired to maintain the bridge’s original character. Thanks to their expertise, the bridge now stands strong and stable, ready to be enjoyed for generations to come.

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’.

A Legacy Preserved

This vital conservation work was made possible through a generous legacy left by one of Wightwick’s dedicated volunteers. The National Trust extends its heartfelt gratitude to all members, donors, and supporters whose contributions have ensured the preservation of this historic feature. Thanks to their generosity, Wightwick Manor & Gardens continues to inspire and delight visitors, preserving its rich history and beauty for all to enjoy.
