Wales is operating country-wide restrictions and is currently at coronavirus alert level four, with strict measures in place to limit the spread of the virus. Please check on the Welsh Government website before visiting or travelling to Wales or within Wales.


Fonmon is one of the few medieval castles which is still lived in as a home. It was built by the St. John family in the early 13th century and has changed hands only once. During the English Civil War Fonmon was sold to Colonel Philip Jones, a direct ancestor of Sir Brooke Boothby, the present owner.

Although most of the present castle dates from the post-medieval period, the rectangular keep was built c.1200 and is still the core of the castle. In later centuries the castle was enlarged by adding wings to the medieval keep accompanied by stunning Georgian interiors.

The castle has many splendid areas open to visitors including the gardens, the hall, the drawing room, the library and the kitchen. On your tour you will hear of the different ways of life and see the different styles of living which have emerged and overlapped as the centuries have passed. Before or after your tour enjoy a stroll around the gardens to see beautiful mature trees from the 19th century, the walled gardens and watch tower.

For groups of 20 or more, bookings are made in advance, both during and outside of normal public opening hours. For such groups, Fonmon Castle can offer a variety of hospitality options; from morning coffee to an evening meal with or without a tour. The most popular option is to combine a tour with a delicious home cooked Afternoon Tea served in the impressive Georgian Library

Public tours can be conducted in Welsh. All other visits (e.g. larger groups) can also be in Welsh, provided we are notified in advance. Fonmon Castle welcome research tours and educational groups at almost any time but these need to be arranged prior to the visit.

Fonmon Castle is a popular licensed venue for civil ceremony weddings and receptions. It is also available for exclusive use hire throughout the year for a wide variety of events and celebrations, both outside in the extensive grounds and gardens and inside with its wealth of history. The Castle can host private parties and dinners, corporate away days or training sessions, company celebrations and due to the fact that it is a still a private home, guests are always assured of a warm and personal welcome with flexible solutions to serve any occasion
