Iconic suspension bridge in Offaly reopened after amazing restoration
With the support of the Historic Structures Fund 2023, the iconic 13.5 metre Birr Castle Demesne Suspension Bridge, one of the oldest bridges of its kind in Europe, has undergone a full conservation restoration.
As part of Engineers Week the bridge re-opened under restricted access to some lucky students Birr Mercy Primary School, marking a significant milestone for the community of Birr and underscoring the commitment of the Demesne to preserving its rich historical heritage.
Crossing the River Camcor, the Birr Suspension Bridge is not only a testament to engineering ingenuity but also holds immense historical significance, being yet another example of technical innovation on the estate that houses the Leviathan of Parsonstown, which was the world’s largest telescope from 1845 to 1917.
Grainne O’Malley, General Manager at Birr Castle Demesne, highlighted the bridge's unique technical features.
She pointed out, "The Birr Suspension Bridge is of significant technical interest as a rare surviving example of a multiple-wire cable suspension bridge, possibly the earliest surviving in Europe, dating between 1821 and 1825. Its historical association with the innovative Parsons family adds another layer of importance. The unusual engineering processes believed to have been used in this rare and early suspension bridge are truly fascinating and we are thrilled to have the next generation of potential engineers on site learning about it. "
The Birr Suspension Bridge remains a symbol of innovation and resilience. Its restoration signals a commitment to preserving not only its historical legacy but also ensuring renewed access across the River Camcor for generations to come.
The exact construction date is a mystery. There is very little mention of the bridge in the Castle archives which date back over 400 years. However, it is mentioned in Cook’s picture of Parsonstown (Birr) in 1826. We can reliably say that it was built sometime between the two dates of 1821 and 1825.
Damien Owens, Director General of Engineers Ireland, commended the combination of heritage and modern engineering skills employed in its restoration.
“I am delighted,” he commented, “that this remarkable feat of engineering has been so carefully and faithfully restored, especially in a place so recognised for engineering marvels. Engineers Week has been created to introduce primary and secondary school children to the diverse world of engineering. What has been restored here will really inspire these students to open their eyes to how engineering is part of everyday life.
“Structural repairs and conservation efforts were integral parts of the restoration project, preserving something that was over 200 years old, and with the works now complete, visitors to the demesne will be able to admire this wonderful structure for generations to come.”
Grainne O’Malley praised the incredible team, who together completed the project seamlessly. "I completely appreciate the knowledge and talents of all those who worked on this unique project,” she said, “combining traditional craftsmanship with modern engineering expertise.
“I would like to particularly mention John Kelly and Aoife Howard of David Kelly Partnership, the conservation experts, with lead engineer Mark Murphy Consultancy assisted by Kieran Ruane of Civic and Structural Engineering Advisors Ltd, and the physical works carried out by Michael Mackey of Mackey Plant Construction.
“Rachel McKenna, Senior Executive Architect with Offaly County Council also supported our successful Historic Structures Fund application in 2023.
“The Birr Suspension Bridge holds a special place in the hearts of locals and visitors alike. It was originally built to facilitate family crossings to St. Brendan's Well (dating back to the 6th Century) and later provided access to the family's private garden. Today, it stands as a cherished landmark within the demesne.
“This bridge is one of only two suspension bridges in Offaly; the other is at Kinnitty Castle and dated 1840 and we would think inspiration stems from this bridge here on the demesne. The Birr Suspension Bridge is one of twenty bridges within the demesne, each contributing to the area's rich tapestry of history and natural beauty.
“As restoration efforts continue, Birr Castle Demesne remains dedicated to honouring its past while embracing the future.” She added that the suspension bridge due to its age, and health and safety concerns, will only open under restricted access.
“Part of Ireland’s Hidden Heartlands,” she added, “and a day trip from many places in Ireland, Birr Castle Demesne is one of Ireland’s most intriguing destinations and a must-see for all ages. A destination for those interested in wildlife, nature, education, science, engineering, astronomy and heritage. We are open daily. A visit to Birr Castle Demesne includes garden walks, seven science galleries, the treehouse playground, the Great Telescope, Forest bathing, and 120 acres of parklands and gardens for you to explore.

“The Engineers Ireland STEPS Programme,” commented Damien Owens, “is designed to open up the exciting possibilities which engineering offers to school children who want to make a real difference in the world.
“During STEPS Engineers Week we introduce primary and secondary school children to the diverse world of engineering by providing practical resources for teachers, such as hands-on activities, a classroom celebration pack and on-demand virtual engineering shows. We encourage engineering organisations to collaborate with their local schools; they can choose from a menu of activities to interact with the students. In our experience, this combination of professional expertise and learning-by-doing inspires children to open their eyes to how engineering is part of everyday life.
