Penrhyn Castle and Garden near Bangor in Gwynedd is an impressive neo-Norman fantasy castle built between 1819 and 1835 by architect Thomas Hopper for George Dawkins Pennant. The castle showcases luxurious interiors including a notable one-ton slate bed, reflecting the wealth generated from the family's north Wales slate mining operations. The surrounding 60 acres feature formal walled gardens, a celebrated 100-metre-long Fuchsia Arch designed in the 1880s by head gardener Walter Speed, and woodland walks with specimen trees. Managed by the National Trust, the property includes a Railway Museum, dolls house museum, and multiple play areas. Year-round attractions encompass snowdrops and spring bulbs transitioning to ornamental features and autumn woodland colors.
