Castell Mynach

Castell Mynach Welcome to Castell Mynach, a beautiful country pub and restaurant in Llantrisant, Mid Glamorgan. We? So, sit back and relax while we take care of the rest.

Whether you’re looking for a long, lazy lunch with family, or a spontaneous mid-week treat with friends, we’ve got you covered. Our beautiful pub and restaurant combines the cosy, rustic features of the countryside with delicious, contemporary food and drink. Our menus change seasonally to offer you the very best, fresh ingredients. And when it comes to refreshment, our fridges are fully stocked w

ith plenty to choose from, including countryside ciders, cask ales, prosecco and carefully selected wines. The name Castell Mynach is Welsh for ‘The Castle of the Monks’, and refers to an old monastery – the ruins of which still stand opposite the pub. After a bite to eat with us, why not make a day of it and discover what’s beyond our walls, including the monastery site and nearby Cardiff. As part of the Vintage Inns family, we’re proud of our heritage and welcoming service which ensures you’ll always receive the Vintage treatment. The countryside is calling.

🚶‍♀️ 100 MILES IN SEPTEMBER! 🚶‍♂️

This September, we’re stepping up for Social Bite and taking on the challenge of walking 100 miles to help raise vital funds for people experiencing homelessness. ❤️

It’s a big challenge, but with the support of our amazing Castell Mynach guests, we’re hoping to make every mile count!

💷 If you’d like to support us, we have a Social Bite donation container at the bar — every little donation makes a difference.

So next time you’re in, why not pop a few pounds in the pot and help us get one step closer to our goal? 👣
