Tullynally Castle, Gothic castle in Castlepollard, Ireland

Tullynally Castle, also called Pakenham Hall, is a grey stone Gothic Revival house of over 120 rooms about 2 km from Castlepollard. A tall square crenellated tower stands at one end, with two storeys of rectangular windows and dormers along the facade, a small gabled porch with a red door near the centre, and a rounded tower with slit windows projecting further right. It sits behind a low metal fence within twelve acres of parkland and gardens.

In 1665 Henry Pakenham, a captain in the Parliamentary Dragoons, was granted the Tullynally land in lieu of pay arrears; a fortified house stood on the site in the 17th century. His grandson Thomas became 1st Baron Longford in 1756, and the 3rd Baron inherited the earldom of Longford in 1794. The 2nd Earl remodelled the house in the Gothic Revival style in the early 19th century, adding towers and a moat.

The house takes its alternative name, Pakenham Hall, from the family that has held it since 1665, when Henry Pakenham received the land in lieu of unpaid wages. General Sir Edward Pakenham, a senior British Army commander, was born and raised here; his sister Kitty married Arthur Wellesley in 1806, later the 1st Duke of Wellington. The grounds open to visitors from April to September.

Visits require groups of at least 20 people and provide access to selected rooms through staircases and towers. Visitors should be prepared for uneven ground on the estate and wear appropriate footwear.

The current owner Thomas Pakenham, a noted historian, planted thousands of trees across the estate. This systematic planting created special walking routes that highlight different tree species.
