Located around a hill in the southern part of the Vale of Clwyd, the older part of the town (population 5,200), the castle and Saint Peter's Square are located on top of the hill.During the English Civil War, Ruthin castle survived an eleven-week siege, after which it was demolished by order of Parliament; rebuilt in the C19th century as a country house, it is now a hotel.
At the former Ruthin Gaol, visitors can spend time exploring its nooks and crannies and learn about life in the Victorian prison system. Ruthin Craft Centre has three galleries, six artist studios, a retail gallery, education and residency workshops, tourist information and a café with courtyard terrace. Nantclwyd y Dre was built around 1435 by a local merchant and is believed to be the oldest surviving town house in Wales.
This restored building contains seven rooms which have been used to represent various periods in the building's history. Dibleys Nurseries, the houseplant specialist, is set within a 10 acre arboretum garden to the south of Ruthin; open to the public, the garden is planted with many unusual specimen trees and shrubs with large numbers of rhododendron, sorbus, hollys, acers and buddleias.
