Seiont (electoral ward)

Afon Seiont is a Site of Special Scientific Interest (or SSSI) in West Gwynedd, Wales. It is protected by law and has been designated as a Site of Special Scientific Interest since July 1997 in an attempt to protect rare or unique features or species within it. The site has an area of 6.4 hectares and is managed by Natural Resources Wales. This site is designated due to its geological qualities. In Wales, geological sites range from quarries to rocky outcrops and massive sea-cliffs. 30% of SSSIs in Wales are notified for geological and geomorphological features. River Seiont is a small river which flows to the sea at Caenarfon, North Wales. Gwynedd County Council and Caernarfon Harbour Trust own this site, with no public access. The west river bank, and also in a past river cliff located 200m inland, is of particular interest for strata. The exposed rocks include the Arenig and overlying Llanvirn series.

Carnarvon (Pant) was the temporary northern terminus of the Carnarvonshire Railway, located on the southern fringe of Caernarfon, Gwynedd, Wales.The line from Afon Wen to Caernarfon was built from the country end, as were the other standard gauge routes to the town, resulting in there being three temporary termini on the edges of Caernarfon. This was eventually resolved by building the "Caernarfon Town Line" through a tunnel under the historic centre to join the various routes. When this was completed Pant station was closed. The station appears to have been built on rented land, as in November 1868 a Mr Rice Thomas threatened to eject the railway from the station for non-payment of rent. The facilities included a platform and a turntable, both still traceable on the land in the 1940s and a siding which acted as an open air engine shed.Freight and passenger trains passed through the edge of the station site until 7 December 1964, when all services were withdrawn. The line was lifted in 1969. In 1997 the Welsh Highland Railway began running through the edge of the station site, having used part of the trackbed for their narrow gauge line to Porthmadog. Sources cited in this article differ on the station's location, research continues.

Carnarvon Castle railway station was opened in 1856 by the narrow gauge Nantlle Railway near the foot of what is today the Allt Y Castell which slopes down to Caernarfon's harbour area. It was the line's northern terminus and was the closest of Caernarfon's ultimately five stations to the historic town centre.

The Aber Swing Bridge, also known as the Pont yr Aber and Caernarfon swing bridge, is a pedestrian swing bridge in Gwynedd, Wales. This footbridge crosses over the Afon Seiont from the foreshore to the Watergate entrance in the centre of Caernarfon near Caernarfon Castle. It was built in 1970, is made of concrete and steel, and is powered with electricity.This bridge replaces another swing bridge which opened on March 1, 1900 (St. David's Day). That first bridge was built to replace the ferry. It was demolished in 1969. For a short time after that, there was a bailey bridge.

Caernarfon Castle (Welsh: Castell Caernarfon Welsh pronunciation: [kastɛɬ kaɨrˈnarvɔn]) – often anglicised as Carnarvon Castle or Caernarvon Castle – is a medieval fortress in Caernarfon, Gwynedd, north-west Wales cared for by Cadw, the Welsh Government's historic environment service. It was a motte-and-bailey castle from the late 11th century until 1283 when King Edward I of England began to replace it with the current stone structure. The Edwardian town and castle acted as the administrative centre of north Wales, and as a result the defences were built on a grand scale. There was a deliberate link with Caernarfon's Roman past, and the Roman fort of Segontium is nearby.While the castle was under construction, town walls were built around Caernarfon. The work cost between £20,000 and £25,000 from the start until the work ended in 1330. Although the castle appears mostly complete from the outside, the interior buildings no longer survive and many of the building plans were never finished. The town and castle were sacked in 1294 when Madog ap Llywelyn led a rebellion against the English. Caernarfon was recaptured the following year. During the Glyndŵr Rising of 1400–1415, the castle was besieged. When the Tudor dynasty ascended to the English throne in 1485, tensions between the Welsh and English began to diminish and castles were considered less important. As a result, Caernarfon Castle was allowed to fall into a state of disrepair. Despite its dilapidated condition, during the English Civil War Caernarfon Castle was held by Royalists, and was besieged three times by Parliamentarian forces. This was the last time the castle was used in war. The castle was neglected until the 19th century when the state funded repairs. The castle was used for the investiture of the Prince of Wales in 1911 and again in 1969. It is part of the World Heritage Site "Castles and Town Walls of King Edward in Gwynedd".

Caernarvon (Morfa) was the temporary western terminus of the Carnarvon and Llanberis Railway, located on the southern fringe of Caernarfon, Gwynedd, Wales. The line from Llanberis to Caernarfon was built from the country end, as were the other standard gauge routes to the town, resulting in there being three temporary termini on the edges of Caernarfon. This was eventually resolved by building the "Caernarfon Town Line" through a tunnel under the historic centre to join the various routes. When this was opened Morfa station was closed on 5 July 1870, though it appears that formal paperwork was not concluded until the following January. Freight and passenger trains passed through the station site until 1930, when regular passenger services were withdrawn. Summer excursions to Llanberis passed through until September 1962 and freight lingered on until the line closed in 1964. The tracks were lifted in early 1965.

Porth yr Aur forms part of the Castles and Town Walls of King Edward in Gwynedd UNESCO world heritage site. Construction began in 1283 at the same time as Caernarfon castle, both integral components of the city walls, and was completed by 1292.
