Fonmon is one of the few medieval castles which are still lived in as a home.

It was built by the St. John family c1200 and in 1656, during the English Civil War it was bought by Colonel Philip Jones, a direct ancestor of Sir Brooke Boothby, the previous owner.

The varied styles of architecture, collections of books, paintings and furniture all tell of its long and distinguished place in Welsh history.

Today Fonmon welcomes visitors in many different ways both as a wedding and events venue and through Public Opening and tours. Come and enjoy a journey through its fascinating history.
