Hillsborough Castle and Gardens

The royal gardens at the home of Northern Ireland’s only royal residence, Hillsborough Castle have almost 100 acres of glorious gardens bursting with colour.

Including ornamental grounds and formal gardens, peaceful woodland, meandering waterways and picturesque glens, an idyllic lake and large walled garden, the gardens are a joy to explore. A key focal point of the gardens is the Lady Alice’s Temple, added in 1867, which offers a good place to contemplate, socialise and seek inspiration. The picturesque Yew Tree Walk is the route of the original road to Moira, which passed in front of the house and into The Square and is now named after the paired Irish Yew trees that line the path.

From swathes of woodland bulbs and the bright show of our daffodil collection in spring, rhododendrons that flower from February to July to the billowing herbaceous borders and scented roses in full summer, colourful acers in autumn to the majestic silhouettes of the ancient oaks in winter, it is truly a garden for all seasons.
