Montalto, nestled beautifully in the heart of the picturesque Co. Down countryside, is a privately-owned demesne which dates back to the early 1600s.

In pre-plantation times the estate was originally owned by Patrick McCartan. However, due to his involvement in the 1641 Rebellion, his Ballynahinch lands were confiscated, and in 1657 the townland was purchased by Sir George Rawdon. Circa 1765, his descendant Sir John Rawdon – First Earl of Moira – built a mansion property on the estate: this is the house that we now know as Montalto House.

Sir John’s ancestor, Sir Arthur Rawdon – The Father of Irish Gardening – had earlier amassed a large collection of exotic foreign plants at Moira Castle. Many of Sir Arthur’s plants were transferred to Montalto when his grandson Sir John moved onto the estate.

The estate has been almost exclusively, a family home since Lord Moira built the first house here. Nowadays Montalto offers visitors the use of 400 acres of rolling Irish countryside, which includes wonderful trails and gardens and a chance to explore this historic demesne and reconnect with nature.
