Plas yn Rhiw is a 16th-century manor house located on the southern slopes of Mynydd Rhiw overlooking Porth Neigwl. The estate was rescued from dereliction in 1939 by the Keating sisters, who meticulously restored the house and established its tiered ornamental gardens. The site is owned and managed by the National Trust and is renowned for its diverse collection of shrubs, trees, and wildflowers. The property is characterized by its traditional white-washed exterior and proximity to the Llyn Peninsula coastline. Its elevated position offers panoramic views across the bay towards the mountains of Snowdonia. The gardens contain a mixture of formal planting and wilder woodland areas that provide habitats for local birdlife. Visitors can access both the manor's interior rooms, which reflect the mid-20th-century aesthetic of the Keating family, and the extensive terraced grounds. The site serves as a vital point for observing the unique microclimate and botanical variety found on the Llyn Peninsula.
