Drysllwyn Castle stands on high ground overlooking the Tywi Valley with extensive views. It was built in about the 1220s by one of the princes of the kingdom of Deheubarth, and changed hands several times in the struggles between the Welsh and English over the ensuing centuries. It is considered one of the most important remaining structures built by a Welsh chieftain.

Drysllwyn was seized by Owain Glyndŵr in the summer of 1403 and when the English forces recaptured it they decommissioned it by blocking various access routes, walling up the gatehouse, removing the treads from stone stairs and even removing the hinges from the main gate. At some later stage, all the major buildings were burned to the ground. Following this a lot of the stone was removed from the site


The polygonal Inner Ward contains principal remains to the south west, with traces of the Middle and Outer Ward to the north east. The early thirteenth century curtain wall to the Inner Ward only stands 1m high. There is a garderobe to the east side, and a remodelled thirteenth century Gatehouse to the north east, surviving at foundation level only. On the south side of the Gatehouse is the Round Tower, the original keep. The foundations of the original Great Hall and Rhys ap Maredudd's hall survive.

Very nice castle ruins. On top of a hill. A bit of a challenge when the temp was 30 degrees. No toilet or food around.

Some of the best views, spectacular viewing point. No charge for car park, has picnic tables, no charge to walk up to castle. Good pathway, most should be able to climb but doesn't look wheelchair friendly as swing gate entry and steps along route up.

Surprising castle from the road only looks like small castle with one wall. Car park just after the bridge. Well worth the climb to the top. More to see of the castle. Great views.

Fantastic Views - Free to visit This castle has breathtaking views of the Towy Valley, there is a decent amount of the structure standing and Cadw provides some information. It’s a bit of a climb up but worth it for the views and history. Well worth a visit if you are in the area. Car park and picnic area is at the base of the hill (before you cross the bridge) Free to park No facilities (toilets, shop etc) I would say it’s Not suitable for wheelchair users due to some steep bits and steps.

Free entry and parking in a beautiful setting makes this an excellent castle to explore. A fairly stiff climb up but plenty of places to get a breather on the way up. Highly rated for its views across the Tywi Valley. No facilities except parking. Please help to keep it looking wonderful and take your rubbish home, there are no bins or collection so let's do our bit to look after this hideaway ourselves

Redipuglia World War I Memorial

Redipuglia is the largest Italian Military Sacrarium. It rises up on the western front of the Monte Sei Busi, which, in the First World War was bitterly fought after because, although it was not very high, from its summit it allowed an ample range of access from the West to the first steps of the Karstic table area.

The monumental staircase on which the remains of one hundred thousand fallen soldiers are lined up and which has at its base the monolith of the Duke of Aosta, who was the commanding officer of the third Brigade, and gives an image of a military grouping in the field of a Great Unity with its Commanding Officer at the front. The mortal remains of 100,187 fallen soldiers lie here, 39,857 of them identified and 60,330 unknown.
