Beaumaris Castle

Highlight • Historical Site

Beaumaris is known as the greatest castle never built. The castle was constructed as part of Edward I's campaign to conquer north Wales after 1282. Whilst Edward and his architect James of St George had grand visions for the castle, lack of funds meant building work petered out in the 1320s. As such, the south gatehouse and the six great towers never reached their intended height and the Llanfaes gate was hardly started before work was abandoned.

A brilliant traffic-free shared use cycle path from the coastline into Conwy. This section of the National Cycle Route 5 (North Wales Coastal Route) that leads through a quiet marina into Conwy is particularly special, and Conwy Castle itself looks like something fresh out of kid’s storybook.

Ednyfeds Castle

Highlight • Castle

The reference to "Ednyfed's Castle" is related to Ednyfed Fychan (c. 1170–1246), a powerful Welsh nobleman, warrior, and ancestor of the Tudor dynasty. He was the distain (seneschal or chief minister) to the Princes of Gwynedd, Llywelyn the Great and his son, Dafydd ap Llywelyn.
Ednyfed's vast landholdings and manors were scattered across North Wales, and he is associated with at least two sites where a defensible residence or "castle" of a Welsh lord would have stood.
What it was: This site, on Bryn Euryn hill, is traditionally believed to be the location of one of Ednyfed's main manors (or llys, a native Welsh court).
The "Castle": The structure associated with Ednyfed would have been an earlier, probably timber, defensive structure like a motte and bailey castle, typical for a Welsh lord of the 13th century.
Current Site: Today, the site is dominated by the ruins of the later 15th-century fortified manor house known as Llys Euryn, which was built on the same spot.

Beaumaris Castle (/bjuːˈmærɪs/ bew-MAR-is; Welsh: Castell Biwmares Welsh pronunciation: [kastɛɬ bɪuˈmaːrɛs]), in Beaumaris, Anglesey, was built as part of Edward I's campaign to conquer north Wales after 1282. Plans were probably first made to construct the castle in 1284, but this was delayed due to lack of funds and work only began in 1295 following the Madog ap Llywelyn uprising. A substantial workforce was employed in the initial years under the direction of James of St George. Edward's invasion of Scotland soon diverted funding from the project, however, and work stopped, only recommencing after an invasion scare in 1306. When work finally ceased around 1330 a total of £15,000 had been spent, a huge sum for the period, but the castle remained incomplete.

Before the English built the town of Conwy, Aberconwy Abbey, the site was occupied by a Cistercian monastery favoured by the Welsh princes,[3] as well as the location of one of the palaces (called llys) of the Welsh princes. From Conwy: "the oldest structure is part of the town walls, at the southern end of the east side. Here one wall and the tower of a llys [palace/court house] belonging to Llywelyn the Great and his grandson Llywelyn ap Gruffydd have been incorporated into the wall. Built on a rocky outcrop, with an apsidal tower, it is a classic, native, Welsh build and stands out from the rest of the town walls, due to the presence of four window openings. It dates from the early 13th century and is the most complete remnant of any of his Llys." The location also controlled an important crossing point over the River Conwy between the coastal and inland areas of North Wales, that Deganwy Castle for many years had defended.
