We were delighted to host the Visit Offaly AGM at Birr Castle Demesne recently and to welcome tourism colleagues from across the county for such a positive and engaging gathering.

It was encouraging to hear about the exciting developments and ongoing work taking place to promote County Offaly as a visitor destination, while also having the opportunity to connect with fellow tourism professionals who are passionate about showcasing all the county has to offer.

Members also enjoyed a guided tour of Birr Castle, exploring the estate’s history, gardens, and scientific heritage.

Our thanks to Visit Offaly and everyone who attended — we look forward to continuing to work together to support tourism across Offaly. 🌿🏰
