Tretower Castle (Welsh: Castell Tretŵr) is a Grade I-listed ruined castle in the village of Tretower in the county of Powys, Wales. It was built around the beginning of the twelfth century as a motte and bailey castle and this was probably replaced mid-century by a stone shell keep. The castle was enlarged in the early thirteenth century, but later fell into ruin.

Tretower Court (Welsh: Llys Tre-tŵr) is a medieval fortified manor house in Wales, situated in the village of Tretower, near Crickhowell in modern-day Powys, previously within the historical county of Breconshire or Brecknockshire.

Tretower (Welsh: Tretŵr) is a hamlet in the community of Cwmdu and District, in the southern part of the county of Powys in Wales. It lies on the A479 road within the Brecon Beacons National Park (Bannau Brycheiniog) at the foot of the Black Mountains just off the Usk Valley. Tretower is frequented by tourists visiting the impressive Tretower Court and the nearby ruins of Tretower Castle, both of which are now managed by Cadw. Cadw own the Court whilst ownership of the Castle lies with the owner of Tyllys Farm in the centre of the village. Tretower Church in the village is dedicated to St John the Evangelist. Though the site is ancient, the present church was completely re-built in 1876–77 after the earlier structure had fallen into disrepair. The Green Man Festival takes place annually in the grounds of Glanusk Park a mile to the south-east of the village.

Llangynidr Bridge, also known as "Coed-yr-Ynys Bridge", is an early 18th-century bridge that crosses the River Usk to the north of Llangynidr, Powys, Wales. It carries the B4560 road towards Bwlch. The existing stone bridge dates from approximately 1700, and is thought by some to be the oldest bridge on the River Usk. It replaced an earlier bridge that was located 500m further west; the sale deeds of a local smithy, dated 1630, contain the first known reference to that earlier bridge, which itself replaced a wooden bridge shown on a land survey of 1587. Llangynidr Bridge lies in the Hundred (county division) of Crickhowell and is similar in style to the Crickhowell Bridge over the Usk, which dates from 1706. It has six arches, which vary in span from 22 to 30 feet, divided by v-shaped cutwaters topped by pedestrian refuges and parapets with plain coping stones. The cutwaters continue up to the parapet, in order to provide spaces for pedestrians to stand to avoid wheeled traffic crossing the bridge. It is 69 m (230 ft) long and the road is 2.4 m (8 ft) wide. It is considered a particularly impressive example because of its height - reducing the danger of flooding - and its location, which gives a good view of the architecture. Llangynidr Bridge is known to have been repaired in 1707, and again in 1822. In 1794 a turnpike gate was set up on the Bwlch side of the river, and the right to collect the tolls was auctioned off in 1800. The turnpike cottage is still standing and was purchased from the Beaufort estate in 1915 by the family of one of the earliest toll-keepers. Theophilus Jones, passing through in 1809, noted that the responsibility for repairs lay with the hundred of Crickhowell. Further repairs were carried out in 2015–16. The bridge has been painted over the years by many artists, notably Sir Cedric Morris, whose painting of the bridge has been purchased for Y Gaer, Elizabeth Wynter and Gwyn Briwnant Jones. A short way from the bridge is a standing stone, 14 feet tall, which stands on a field boundary. The bridge became a Grade II listed structure in 1952; it was upgraded to Grade I in 2003 as one of the best early road bridges in Wales, ranked equally with Crickhowell Bridge.

Llygadwy is a locality near the village of Bwlch in the county of Powys in southeast Wales. The usual meaning of llygad in Welsh is 'eye' but it can signify a spring e.g. Llygad Llwchwr. The name therefore signifies the source of a stream known traditionally as 'Yw' though which is nowadays known as Ewyn Brook and which flows through a wide, though short, vale known traditionally as Ystradyw. The modern spelling appears to be a corruption of an earlier form Llygadyw. The spring arises where a band of non-marine limestone known as a calcrete outcrops within countryside otherwise dominated by sandstone rocks of the Old Red Sandstone.

The Rhiangoll is a river in the Brecon Beacons National Park in Powys, Wales. It rises on the western slopes of Waun Fach, highest point of the Black Mountains (Welsh: Y Mynyddoedd Duon) and drops steeply down to the west into the north–south valley through which the A479 runs between Talgarth and the hamlet of Tretower and through the village of Cwmdu. It is joined by various minor tributary streams on its left bank including the Ffinnant, Nant yr Ychen, Nant-y-fedw and Nantygarreg, all of which rise on the flanks of the ridge extending between the Pen Trumau spur of Waun Fach and Pen Gloch-y-pibwr. Two tributary streams flowing from Mynydd Troed and Mynydd Llangorse enter on its right bank as does Nant Ewyn east of the village of Bwlch. The main valley was excavated by glacial ice during the course of the ice ages as it breached the watershed at Pengenffordd. Its broad lower section was influenced by the merging of the Rhiangoll valley ice with that of the main Usk Valley glacier which swept down past Bwlch. The Rhiangoll itself enters the River Usk near Glanusk (or 'Tower') Bridge 1 mile south of Tretower.

Bwlch (Welsh for 'a pass') is a small village and an electoral ward in the community of Cwmdu and District, Powys, south Wales. The settlement is strung out along the A40 road which crosses a low col above the Usk Valley at this point on its route between Brecon and Crickhowell.

Glanusk Park (Welsh: Parc Glanwysg) is a country estate in Wales, United Kingdom, situated near the town of Crickhowell, Powys and was established in 1826 by ironmaster Sir Joseph Bailey. The park features in the hereditary title Baron Glanusk which was given to Sir Joseph's grandson, Sir Joseph Bailey in 1899 who at that time was the Lord Lieutenant of Brecknockshire.

There are 400 acres (160 ha) of private parkland and 800 acres (320 ha) of forest which also includes a collection of over 200 different species of oak trees. Glanusk Park and Estate is privately owned by the Legge-Bourke family. It is situated in the countryside of the Usk Valley, South Wales in the Brecon Beacons National Park, and is one of the largest privately owned estates in Wales. The Victorian gardens and parkland are listed at Grade II* on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales.

The Afon Crawnon is a river in the Brecon Beacons National Park in the county of Powys, Wales. The headwaters rise on the hills north of Trefil and flow northeast down a valley known as Dyffryn Crawnon for 7 km to a confluence with the River Usk just west of Llangynidr. The valley is notable for being at the centre of a major green energy initiative known as The Three Green Valleys project and which involves the construction of several micro-hydro schemes. Dyffryn Crawnon is translated from Welsh to mean "Valley of the Garlic River".
