About Cestyll

The garden was originally part of Cestyll House, bought in 1918 by the Hon. William Walter Vivian of Glyn, Bangor as a gift for his niece Hon. Violet Vivian, a great friend of Princess Victoria. Violet Vivian used Cestyll as a summer home creating a picturesque garden that highlighted the rocky landscape with an escarpment, cliff and bridges over the stream. Fir trees were planted as a wind break and soil was carried to the gardens to allow 3,000 annual plants to be planted each season. As a result of Violet Vivian’s friendship with Princess Victoria, there were many royal visits to the garden and it was Princess Victoria who designed the south west corner of Cestyll. More recently Cestyll is managed in a sustainable way with permanent planting and wildlife habitats.

Cestyll is also home to an old water mill, owned by the National Trust. Known as Felin Cafnan.
When in use the race water would flow over the top of the mill wheel (an overshot wheel) when milling and diverted under the mill when not required.
