The path from the harbor towards Penrhyn Castle and on to Bethesda is a former railway bed, originally built specifically for the transport of slate from the local quarries. This stone bridge, known as Cegin Viaduct, commemorates that railway history. As the oldest known multi-arch railway bridge in Wales (built between 1798 and 1800), the viaduct is internationally important as a historic industrial monument and is listed (Grade II). The bridge has three arches, approximately 26 meters long between each abutment, 5 meters wide, and 3.2 meters high. Each arch has a span of 5 to 6 meters and a height of approximately 1.8 meters. The viaduct was thoroughly restored in 2015. Sources: ygc.cymru/project/cegin-viaduct-restoration-porth-penrhyn-bangor coflein.gov.uk/en/site/401047/

Here you cross the mouth of the Cegin River into the Menai Strait. Here is Port Penrhyn, once a vital port for the export of slate from the Penrhyn Quarry, the largest slate quarry in the world at the end of the nineteenth century. The quarry and the harbour were connected by the Penrhyn Quarry Railway. This is also the starting point of the Snowdownia Slait Trail, a 134km loop that leads hikers through the history of the slate industry.

Nice station building featuring the fanous sign with the 58 character long name of the place, which is commonly used in one of its shorter forms. At the tourist trap on the other side of the parling lot is a translation into English, while the sign on the platform provides pronounciation guidance. Probably besides the Marquess of Anglesey's Column the only really highlight in this place.

Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch The name was coined by a Welshman after the railway line was established in the 19th century to entice tourists to disembark. It still attracts tourists today. Translated into English, the name roughly means: St. Mary at the White Hazel Pool next to the rapids and St. Tysilio Church near the red cave.

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.
