St Quintins Castle site was first occupied with a defensive structure in about 1102 and the gatehouse and further building work took place around 1312. It was later used as a prison and was reported as being in a ruinous state by 1741.

Around 1102 Robert Fitzhamon, the first Norman Lord of Glamorgan bequeathed the lands of Llanblethian as a lordship to Herbert de St Quentin who is thought to have built the first fortification at the site of the castle. This initial construct was believed to have been a simple ringwork defence with timber walls, a bank and ditch. A rectangular stone keep was built in the late 12th century, whose remains can now be found within the later gatehouse. This keep may have replaced a similar wooden structure.

The lordship remained with the St Quentin family until 1233 when the land was seized by Richard Siward, but he then lost it to Earl Richard de Clare in 1245. Richard de Clare seized large areas of this part of Glamorganshire, from Cowbridge to Llantrisant, but it was his grandson, Earl Gilbert de Clare, who began to build the stone structure of St Quintins Castle which stands today. This was thought to have been roughly after 1307, but Gilbert de Clare was killed in the Battle of Bannockburn in 1314 before the castle was completed. Modern historians believe that the lack of inner courtyard buildings and the weakness of the curtain wall points to the hypothesis that the castle was never fully completed.

The castle itself is a rectangular stone walled enclosure, roughly 64 metres East to West. The walls are roughly 120 centimetres in thickness. It is set on a spur above steep slopes on all sides apart from the East side. The weak East side of the fortification is protected by a twin-tower gatehouse and a further two towers East entrance facade. The best defensive side is the southern side which falls away sharply to the River Thaw. It was reported as being ruinous by 1741.

The base of a semi-octagonal tower can be seen at the southeast corner of the castle and parts of a tower at the southwest corner. The ivy-clad gatehouse is between these and is a substantial structure where you can see the slits for the two portcullises and the fittings for the sets of strong doors. The remains of the keep are largely rubble and little remains of the bailey walls on the east, north and south sides.

Lovely remains of a Castle, although it says on the website and the sign outside,it's open , some of the doors are locked and no one came to open them , still it's a great place for a picnic ,There's even a free car park for about 6 cars .

A nice little ruin, ideal for a picnic in the sunshine. Car park is right next to the gatehouse with adequate litter bins at the entrance. A little more information would be nice but we enjoyed our visit. Worth popping in if you are in the area.

Trondenes Church

Trondenes Church is the northernmost medieval stone church of Norway. Though frequently mentioned as a 13th-century church, dating based on dendrochronology places its completion shortly after 1434. Compared to the other ten north Norwegian medieval stone churches, Trondenes church is well preserved and the exterior is close to the original state. The nave is 22.6 metres long and the chancel is 13.5 metres, making it one of the largest medieval churches of rural Norway. In the late Medieval period, Trondenes served as the main church centre of Northern Norway.

The church is especially known for its rich decorations, including three gothic triptychs, one of which is made by the German Hanseatic artist Bernt Notke. The baroque pulpit is equipped with an hourglass to allow the minister to time long sermons. The organ dates from the late 18th century. In the choir section, one can see remnants of medieval frescoes.

The church is probably the third church on the site, the first stave church was built in the 11th century, the second in the 12th. The second church was fortified with stone walls and ramparts, remnants of which can be seen around the church.The church used to have a little turret, which was demolished. Now the bells are rung from a little tower in the graveyeard.
