Dolbelydr Open Days

Trefnant, Denbighshire

Saturday 20 - Sunday 21 September 2025, 10am-4pm

Book free tickets


Dolbelydr, a fine example of a 16th-century gentry house, has good claim to be the birthplace of modern Welsh - it was here that Henry Salesbury wrote his Grammatica Britannica, the first Welsh grammar.

Dolbelydr will be open as part of Cadw Open Doors and the free open days will be an opportunity to see inside this important local landmark and learn more about its history and restoration. Whilst booking is not essential we would ask that you register for the event via Eventbrite so that we can provide you with updates regarding the event.

Opening on the same weekend is Bath Tower in Caernarfon. 

  • Feel free to bring a picnic to enjoy in the grounds. 
  • Free Admission and leaflets on the building's history available.
  • Please note, parking is limited on site.

Making a donation as part of your visit

We believe that everyone should have the opportunity to visit a Landmark for free as part of our Open Day programme, and as such we’re pleased to continue to offer free entry at all our Open Days in 2025.
The Landmark Trust is a building conservation charity that relies on donations to support its work. Over the past 60 years, public support has helped us rescue over 200 historic buildings and make them available for all to experience and enjoy. Your support by attending our events, booking a workshop, and making a donation allows us to continue to save buildings at risk and continue to maintain those already in our care. Your donation could help train the craftspeople needed to restore a future Landmark, offer opportunities for young people to experience history first-hand, or provide a charity with free Landmark stay for their service users through our 50 for Free scheme.

Donations can be made when you book your Eventbrite ticket, at the event via contactless donation points, or after your visit via our website under Support. 

Open Day entry

Due to the historic nature of our buildings we have a limited capacity for our Open Day events. You may therefore be asked to wait a short time while other visitors finish their visit. Whilst booking is not essential, priority will be given to those who have booked in advance. Thank you for your co-operation.

Finding us

Dolbelydr can be a little tricky to find. Please note 'Dolbelydr' on Google maps will not take you to the correct location. 

Follow these directions and look out for red Open Day signage:

Just after entering the outskirts of St Asaph, turn left at the mini roundabout (by the Cathedral) and continue on the A525 to Trefnant. At the traffic lights in Trefnant village turn right on to the B5428 signposted Henllan. (If travelling from Denbigh on the A525 turn left at the traffic lights in Trefnant village on to the B5428)

Follow the B5428 road over a small crossroads and continue for about another half mile. On the left is a gateway and a small lodge and immediately after, on the right, is the entrance to Bryn Wgan Farm (a brown BRYN WGAN sign is attached to the right gate pillar of the entrance).

Turn right down this private lane and follow it until just before you reach the farmyard. The access track to Dolbelydr is through the gate on your right opposite a large oak tree.
