Just 7km away from Castletown House is Maynooth Castle. As with Castletown, Maynooth Castle is also operated by the Office of Public Works.

This great stone castle was founded in the early thirteenth century and became the principal residence of the Kildare branch of the Geraldines. The Kildare FitzGeralds extended their land holdings and influence, emerging as one of the most powerful families in Ireland with Maynooth Castle being one of the largest and richest Earl’s houses. Garret Mór, known as the Great Earl of Kildare, governed Ireland in the name of the King of England from 1487-1513 and under his son, Garret Og the 9th Earl, the Castle became the centre of political power and culture. The original Keep, constructed c. 1203, was one of the largest of its kind in Ireland. Early in the seventeenth century the castle was remodelled and the main focus of the Castle shifted from the original Keep to the buildings in the east of the grounds. It was vested in the State in 1991 and a programme of restoration commenced in February 2000. There is an exhibition in the Keep on the history of the castle and the family.

A couple of other nearby significant heritage buildings which have historic links with Castletown may be of interest. These are Carton House and Leixlip Castle. Read on for more details on both.

Much of Castletown’s beautiful interior decoration was the achievement of Lady Louisa Conolly in the 1760s and 1770s. Louisa came to Castletown House after her marriage to Tom Conolly. They had no children and Louisa instead devoted much of her energies to improvements to the house and demesne at Castletown. The Staircase Hall, Dining Room, Print Room and Long Gallery are amongst the rooms that can be considered symbols of her contribution to the house. (See photos of all of these in our Online Tour here.) Castletown in these years again became a lively, hospitable place with a constant stream of visitors including everybody from the Lord Lieutenant to London actress Sarah Siddons.

Carton, to the north east of Castletown, was where Lady Louisa had spent most of her childhood. Carton was also the home of her sister Emily, first Countess of Kildare and later Duchess of Leinster. Much of the work that Louisa carried out on Castletown’s interior was guided by the advice of her brother-in-law, the Duke of Leinster. Just as Louisa had improved Castletown, so Emily had also created beautiful rooms, follies, and landscaping at Carton. Today, Carton House is a hotel, where you can enjoy a coffee pitstop on your travels, while admiring many original features of eighteenth-century rooms.

Castletown House was built in the 1720s by the Speaker of the Irish House of Commons, William Conolly. Before he built Castletown, he lived at Leixlip Castle, and it was here that his son Tom was born (Tom would go on to marry Louisa, described above). The first thing that you may notice on coming through Castletown’s front door, above the mantelpiece in the Entrance Hall, is a painting with a view of Leixlip Castle. This has been attributed to Joseph Tudor (d. 1759).

Dating from the twelfth century, the Castle has been occupied by many owners; since the 1950s it has been owned by the Guinness family. A splendid collection survives at Leixlip Castle, from Chippendale chairs in the Dining Room, to a seventeenth-century tapestry in the Front Hall, to a remarkable eighteenth-century dolls house in the Drawing Room. The gardens boast a conservatory, a temple, and a fine walled vegetable garden.
