The Overlook & Paula Hayes Garden
To recreate the magical setting of the Overlook rising from the environment, Lyndhurst tasked contemporary land artist and sculptor Paula Hayes with creating a new permanent installation around the structure. The artist-designed garden is comprised exclusively of native plants, many of which appear in early 20th-century horticultural catalogs in our archives. Hayes has also created four sculptures drawing on Victorian garden vernacular: a birdbath, two gazing balls, and a garden gnome. The installation is loosely based on the form of a mandala and provides multiple opportunities for interaction and discovery.

The Overlook is a recreation of the original treehouse deck Helen Gould built as a landscape feature to complement the shady rockeries installed by the Merritt family in the 1860s, which vanished from the landscape in the 1960s. In 1892, Helen Gould assumed ownership of Lyndhurst after her father, Jay Gould, died. During the stewardship of her beloved family home, she added additional buildings and amenities to the estate grounds, including the Kennel Building, Bowling Alley, Laundry Building, Pool Building, Rose Garden, and Fern Garden. These are all still standing on the grounds today.
Just off the back of the mansion to the west, Helen also had what is referred to as a treehouse, but was in actuality a large raised deck built around a large European white birch tree. Not much information survives about the treehouse and its conception, aside from photos of it shrouded in branches, but it is believed to have been built around 1905 as part of a picturesque landscape first introduced in the 1860s by the Merritt Family that included shrubbery tunnels, shaded seating areas, plant borders, and vistas of the Hudson River. This pathway began on the mansion’s veranda and led down to the bowling alley, built in 1894. After Helen’s death in 1930, the treehouse fell into disrepair and was removed from the landscape sometime in the 1960s, around the same time that the walkways were removed as the site was being organized to become a museum.

The recreation of the treehouse is based on historic photographs and on archeological evidence revealing the original location of the birch, supports for the steps, and the original cement step, still in the ground. Eventually, a tree will be planted nearby as we continue to fill it in.
The Garden at the Overlook is a pollinator-friendly garden full of low-maintenance native plants, including flowering shrubs and perennials, and ornamental grasses. Designed by Hudson Valley landscape artist Paula Hayes, it forms a circular pattern, a mandala of plants, around the newly recreated Overlook deck.
Mandalas often represent unity, harmony, and a sense of connection. The individual beds in the garden – Swaths of tall grasses that evoke a strong sense of movement and groupings of colorful flowers – will evolve over time, merging into a meadow. While akin to the wilder style of garden design today, this design supports the 19th-century gardening principles of Helen Gould, an avid naturalist whose library included books on ornithology, native trees, and beneficial insects. Helen’s additions to the Lyndhurst landscape included flowering shrubs and extensive perennial beds. Today, the Overlook & Garden, at the site of her former treehouse, is an example of the evolution of the American landscape and our need to evolve with it through biodiverse plantings and sustainable landscaping practices as the environment changes. Standing atop the platform, visitors are surrounded by plants that benefit bees, insects, and birds, reminding us of the joys of connecting with nature.
