Altamont House

Altamont House is a manor standing near the River Slaney with ornamental gardens, a lake, and extensive woodland across the estate. The grounds feature an ice age glen, bog garden, and arboretum, with walking paths that wind through ancient oak trees and offer views toward the Wicklow and Blackstairs mountains.

The main building took shape in 1740, with significant expansions added during the 1840s by the Dawson Borrer family. The Lecky Watson family acquired the property in 1923 and developed the gardens into their current form.

The Lecky Watson family acquired the property in 1923, developing extensive gardens with rare plant collections, including rhododendrons and azaleas.

The grounds are best explored on foot using the network of paths throughout the estate. Wear sturdy shoes, as the terrain varies from woodland tracks to open areas and can be muddy depending on the season.

A Wellingtonia tree, also called Giant Redwood, stands in the gardens as a memorial to the Battle of Waterloo. This rare North American species was planted as a lasting tribute and remains one of the most distinctive features of the property.
