The property was
presented as a gift to the Irish |
 |
Nation in 1945 and was
later occupied by the Department of Agriculture who established an
agricultural institute here and undertook to maintain but not to
alter the ornamental grounds.

The
Kilkenny architect Daniel Robertson, who was responsible for some
of the building work on the castle, is generally believed to have
laid out and planted much of the grounds in the 1830s. This would
have included the digging of the five-acre lake opposite the
castle with Gothic towers rising from its waters and a terrace
lined with statues on the opposite bank. Many fine trees and
shrubs grow in the vicinity of the castle,
including two lovely examples of Cryptomeria |
|
japonica 'Elegans',
several very fine redwoods (Sequoia sempervirens), a huge Rhododendron arboreum and some of the oldest and largest
specimens of Monterey cypress (Cupressus macrocarpa) in
Ireland. The variety of mixed planting around the lake, which
includes noble
firs,
Japanese cedars, Atlantic blue cedars, copper beeches, golden
Lawson cypresses and holm oaks, provides a very satisfying range
of colour through much of the year. In the area to the west of
the castle lake, visitors will pass through a woodland garden
created around the ruined
medieval castle of Rathlannon. |

| Here the exotic foliage of a
Magnolia
wilsonii from China borders a large, elegant dogwood (Cornus
kousa) from Japan and a Japanese
snowball (Viburnum plicatum) with tiered |
 |
spreading
branches. Nearby lies a two-acre lake dug in the 1860s, while in
the area to the north is a four-acre walled garden built between
1844 and 1851 and rehabilitated by the Department of Agriculture.
.
This is entered
through the Devil's Gate, an arched |
| gateway with gargoyles that
leads onto a very long gravel path lined with flower borders and
backed by clipped hedges. To the tight across mowed lawns a long
hothouse shelters a colourful display of plants through out the
year. Steps lead to the Upper Garden, now largely devoted to shrub
propagation, and the old melon yard. Here no one will fail to
admire a tender dwarf Japanese maple planted in the 1880s and a
range of azaleas, magnolias and hibiscus. |

Other
attractions at Johnstown include a cemetery with very fine
wrought-iron gates made in Italy, the site of the sunken Italian
Garden close to the car park, and the lower lake, dug in the 1850s
and covering some fourteen acres. All three lakes in the demesne
provide a home for a wide range of waterfowl - mute swans, moorhens,
coots, little grebes, herons and a recently introduced flock of
mallards - all of which help to control the waterweeds. The
attractive early nineteenth century farm buildings to the north of
the lower |
 |
| lake house the Irish Agricultural Museum where
a variety of old horticultural implements are on display. |
