The Person Behind the Research

Mairead's path into heritage conservation wasn't straightforward. She grew up in Cork, fascinated by old buildings and the stories they held. During her undergraduate years at UCC, she developed a particular interest in how historic spaces — especially gardens — revealed so much about the people who created them. What started as curiosity about Victorian garden design became something deeper: an understanding that these spaces mattered not just as historical artifacts, but as places where real people lived their lives.

After completing her Master's thesis on Victorian walled gardens in County Waterford, she joined the Irish National Trust's conservation team. That's where she spent eight formative years learning the practical side of heritage work — the actual boots-on-the-ground experience of managing restoration projects, working with communities, and dealing with the messy reality of preserving old things. Theory and practice aren't always aligned, and she learned to navigate that tension early on.

The turning point came in 2015 when she pioneered an accessibility audit framework specifically for older visitors at historic garden sites. She'd noticed something simple but important: heritage organisations were often caught between two seemingly incompatible goals — preserving authenticity and making sites actually usable for people with mobility challenges. She believed they weren't incompatible at all. With thoughtful design, you could honour historical accuracy while making the experience genuinely accessible. That framework is now adopted across Ireland.

What drives her is straightforward: the belief that cultural heritage shouldn't be gatekept by physical limitations. She's passionate about proving that good design can respect both history and people. At frasercedar Ltd, she brings this lived experience to every article, ensuring her writing reflects scholarly depth alongside genuine understanding of what makes heritage tourism rewarding for visitors over 60.

"Heritage shouldn't be gatekept by physical limitations. Thoughtful design can honour both historical authenticity and modern accessibility needs."
