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

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.
