The wonderful quirky Dewstow Gardens

Dewstow Gardens and Grottoes, near Chepstow

Dewstow Gardens and Grottoes is one of the least known of all the attractions in South Wales, but also one of the most interesting.

The Dewstow Gardens, near Chepstow (THE FORGOTTEN GARDENS) are a wonderful place to wander around, with beautifully landscaped paths and decorative beds, rock gardens, waterfalls and many ponds, but it's Dewstow Grottoes that make this place really fascinating.
It’s amazing to think that just over 10 years ago, this strange and wonderful garden was buried beneath thousands of tons of soil, lost and forgotten for over half a century.
Built around 1893, Henry Oakley created a garden – his own personal wonderland – that was described by the few who visited as a “magical and wondrous place”.
When Oakley died in 1940, the gardens fell into disrepair, and were eventually buried and returned to farmland just after ww2. After a huge excavation and renovation project beginning in 2001, the gardens are now open to visitors throughout the summer.

Dewstow Gardens 2019 opens 30  March - see website for details.
Disabled Access. There is very limited access for wheelchairs in the garden and no access to the underground areas.
We have disabled toilet facilities in the tea room area.
