Gwydir Castle, a mile west of Llanrwst in the Conwy Valley, is a Tudor courtyard house built mainly in the 1490s by the Wynn family, the most powerful Welsh gentry dynasty of the Tudor period. It is a lived-in family home rather than a heritage attraction, which gives it an atmosphere that few comparable historic houses can match. The peacocks that wander the courtyard seem to have been there longer than anyone can remember.
The house is open for guided tours and also operates as a bed-and-breakfast — staying the night puts you inside a grade I listed building that has barely changed since the Wynns were building it. The gardens, laid out in the 16th and 17th centuries, are themselves listed as of special historic interest, with yew hedges, a cedar of Lebanon planted in 1625, and a walled garden that looks unchanged from the period. It is about 15 minutes by car from Conwy town.
