October 23, 2022, Gorsedd Stones, Haverfordwest

Gorsedd Stones are arrangements of standing stones constructed for the National Eisteddfod of Wales for each one. They are scattered throughout Wales and are a nice surprise when you come across one unexpectedly. This particular group of stones was constructed for the Eisteddfod in 1972. https://en.wikipedia.org/wiki/Gorsedd_stones https://www.dreamstime.com/gorsedd-bards-circle-haverfordwest-pembrookshire-stones-are-arrangements-of-standing-stones-constructed-the-national-image101698853

The entrance to Haverfordwest Priory is easily missed. Haverfordwest Priory has the only surviving remains of an ecclesiastical medieval garden in Britain. Parts of the church, chapter house and cloister also remain.

Although it’s impressive from the riverside, very little of the castle remains other than the outside wall. Several towers on the south east and south west corners are still standing but there’s no access to the ramparts. The town museum can also be found in a building inside the outer keep of the Castle. Entry is £2, Open Monday to Saturday, 10 a.m. to 4 p.m.

Park free unlimited outside Halfords, take the cycle path to Merlin's Bridge where you can pick up the Brunel Trail to Neyland. The Bakery at Johnstone by the train platform does superb pulled pork rolls or you can get an excellent meal at the cafe in Neyland Marina to fortify you for the return gradient.

The Brunel Trail is a fantastic traffic-free route for walkers, runners and cyclists that links Neyland (formerly the most western point on Brunel's Great Western Railway) to Johnston and Haverfordwest. The route is predominantly tarmac and forms part of the National Cycle Route 4 and Celtic Trail.
