WorldYellow In detail

Mallwydd is an ancient site in Gwynedd near the border with Powys. According to tradition, already in the 6th century there was founded a Christian church.

The current church was built in the 14th century with multiple later rebuildings. This is an interesting church and, among other artefacts, there are also two enormous bones that, according to local tales, were unearthed in this area.

In the late 18th century in the churchyard of St Tydecho’s Church were five enormous yew trees. The largest of them still is there.

In 1998 the circumference of the giant yew at Mallwyd St Tydecho’s Church was 10.06 m (1.). It was measured at a height of 0.9 m. But today this male yew is not a single stem anymore: the hollow of the tree gradually increased and divided the yew tree into three main parts. Each of these three parts consists of several large trunks – branches. Similar to several other ancient yew trees, there is also a new stem in the centre of the hollow.

In the churchyard is one more enormous yew tree – female – that has a circumference of 5.64 m at a height of 1.5 m (1998, 1.).

The giant yews of Mallwyd have been well known for centuries long. In 1798 the largest tree had a circumference of 27 feet – 8.2 m. The tree had a single trunk until the middle of the 19th century at least.

The God Tree

The God Tree is a great read and will make people think again and again about Yews’ – David Bellamy, the Naturalist. This is the first book to take up the quest for the Golden Bough since JG Frazer’s classic study in 1915 with the discovery of the bough growing once more, as the rare adornment of a small number of ancient Yews.

The Ancient Yew: A History of Taxus baccata

The gnarled, immutable yew tree is one of the most evocative sights in the British and Irish language, an evergreen impression of immortality, the tree that provides a living botanical link between our own landscapes and those of the distant past. This book tells the extraordinary story of the yew’s role in the landscape through the millennia, and makes a convincing case for the origins of many of the oldest trees, as markers of the holy places founded by Celtic saints in the early medieval ‘Dark Ages’.
