Penrhyn Castle (Welsh: Castell Penrhyn) is a country house in Llandygai, Bangor, Gwynedd, North Wales, constructed in the style of a Norman castle. The Penrhyn estate was founded by Ednyfed Fychan. In the 15th century his descendent Gwilym ap Griffith built a fortified manor house on the site. In the 18th century, the Penrhyn estate came into the possession of Richard Pennant, 1st Baron Penrhyn, in part from his father, a Liverpool merchant, and in part from his wife, Ann Susannah Pennant née Warburton, the daughter of an army officer. Pennant derived great wealth from his ownership of slave plantations in the West Indies and was a strong opponent of attempts to abolish the slave trade. His wealth was used in part for the development of the slate mining industry on Pennant's Caernarfonshire estates, and also for development of Penrhyn Castle. In the 1780s Pennant commissioned Samuel Wyatt to undertake a reconstruction of the medieval house. On Pennant's death in 1808, the Penrhyn estate was inherited by his second cousin, George Hay Dawkins, who adopted the surname Dawkins-Pennant. From 1822 to 1837 Dawkins-Pennant engaged the architect Thomas Hopper who rebuilt the house in the form of a Neo-Norman castle. Dawkins-Pennant, who sat as Member of Parliament for Newark and New Romney, followed his cousin as a long-standing opponent of emancipation, serving on the West India Committee, a group of parliamentarians opposed to the abolition of slavery, on which Richard Pennant had served as chairman. Dawkins-Pennant received significant compensation when, in 1833, emancipation of slaves in the British Empire was eventually achieved, through the passing of the Slavery Abolition Act. In 1840, the Penrhyn estate passed to Edward Gordon Douglas, through his marriage to Dawkins-Pennant's elder daughter, Juliana. Douglas, who assumed the name Douglas-Pennant, was elevated to the peerage as 1st Baron Penrhyn of the second creation in 1866. He, and his son and heir, George Douglas-Pennant, 2nd Baron Penrhyn, continued the development of their slate interests at Penrhyn Quarry, and of the supporting infrastructure throughout North-West Wales. Firmly opposed to trade unionism at their quarries, their tenure saw bitter strikes over union recognition and workers' rights, culminating in the Great Strike of 1900–1903, the longest dispute in British industrial history. Little development took place at the castle, which was not the family's principal residence and was mainly used as a holiday home in the summer months, but the interior was enhanced by Edward Douglas-Pennant's creation of a major collection of paintings. These provided the setting for entertaining guests, who included Queen Victoria, her son the Prince of Wales and William Gladstone. The castle passed from the family to the National Trust via the National Land Fund in 1951. Penrhyn Castle is a Grade I listed building, recognised as Thomas Hopper's finest work. Built in the Romanesque Revival style, it is considered one of the most important country houses in Wales and as among the best of the Revivalist castles in Britain. Its art collection, including works by Palma Vecchio and Canaletto is of international importance. In the 21st century, the National Trust's attempts to explore the links between their properties and colonialism and historic slavery have seen the castle feature in the ensuing culture wars.

The Battle of Y Dalar Hir took place on 5 June 1648 in Caernarfonshire, North Wales, during the Second English Civil War. While little more than a skirmish, it had a significant effect on the local progress of the conflict.Leading Welsh Royalist Sir John Owen of Clenennau mustered a group of 250-300 cavalry and foot in an attempt to raise North Wales in rebellion against Parliament; on 3 June he defeated local militia in a skirmish near Caernarfon and besieged Caernarfon Castle. Colonel George Twisleton, Parliamentarian governor of Denbigh, confronted Owen at Y Dalar Hir on the shore of the Menai Straits near Llandegai, where the Royalists were scattered and Owen captured, effectively ending the spread of the rebellion in North Wales.

The Afon Cegin (River Cegin in English) is a small river draining parts of North Wales and discharging to the Menai Strait at Porth Penrhyn. Its name means Kitchen River in English.

Port Penrhyn (Welsh: Porth Penrhyn) is a harbour located just east of Bangor in north Wales at the confluence of the River Cegin with the Menai Strait. It was formerly of great importance as the main port for the export of slate from the Penrhyn Quarry, the largest slate quarry in the world at the end of the nineteenth century. It was built, and later expanded, by the Pennant (later Douglas-Pennant) family of the nearby Penrhyn Castle. Penrhyn is the Welsh word for 'promontory'. The port is used by coastal vessels up to about 3,000 tonnes deadweight (DWT) and by fishing vessels.

River Adda (Afon Adda in Welsh) is a small watercourse which flows, through the city of Bangor North Wales before discharging into the Menai Strait at Hirael Bay, opposite Porth Penrhyn. The name is said to be of 19th-century origin, deriving from a field Cae Mab Adda (the field of the son of Adam) close to its source. Its earlier name was Tarannon.Lon Las Adda (a foot and cycle path) follows closely the course of the river for much of its length. By this path at Glynne Road can be seen the sides of an old bridge. Now for the most part culverted, parts of the river were open up until the 1960s. The last section, from Glynne Road to Beach Road was culverted prior to the building of the nearby swimming pool. Following flooding in the Caernarfon Road area in 2004, a flood alleviation scheme was carried out by the (then) Environment Agency Wales to improve the culverting. Work was completed in 2008. In 2016 Dr Zoe Skoulding and Ben Stammers ran a project called rAdda, which was supported by a number of statutory and other bodies. The project sought to explore the relationship between the river, and the people of Bangor. It included an interpreted walk along the course of the Adda, and a multi-media performance in Storiel gallery, which featured photographs; spoken, and recorded words, and music.

Victoria Terrace, on the seafront in Beaumaris, Anglesey, Wales is a range of early 19th century townhouses. The terrace was designed by the architectural partnership of Joseph Hansom and Edward Welch for the Beaumaris Corporation.

The terrace was sold off in the early 20th century and is now divided into nineteen apartments. No. 1 remaining as a single house. This, and each apartment, No.s 2-20 inclusive, is designated a Grade I listed building, the Cadw listing record describing the whole block as "an outstanding and well-preserved late-Georgian terrace of national importance".
