Logan Botanic Gardens, Ardwell

Logan Botanic Gardens is an early 19th century walled garden that includes the remains of a castle, along with a Gardener's Cottage and associated buildings.

The walled garden features south and east walls made of rubble with rubble coping, while the north and west walls are primarily brick with flat concrete coping. There is a gateway with a simple iron gate located to the south, situated in a section of wall between the Gardener's Cottage and the Bothy. At the center of the west wall, remnants of the castle are incorporated, featuring a tall rubble section with additional rubble wall sections on both sides. Below the castle, a series of cascading terraces made of rubble with red sandstone flat coping and red sandstone steps can be found. An internal brick wall runs east-west at the center of the garden, which has a modern gateway cut through it and a modern brick lean-to gazebo attached at the southern side.

In the garden, there is a square pond that contains two decorated urns on pedestals within the water, along with sandstone stepping stones crossing one corner of the pond. The Gardener's Cottage, Bothy, and outbuildings to the south interrupt the wall and are made of painted rubble.

The Gardener's Cottage is a two-storey, three-bay house with the first floor breaking the eaves. It features painted brick margins. The south elevation has a gabled porch at the center with decorative bargeboarding on the overhanging eaves and modern brick piers. There are windows in both floors of the outer bays, and broad gabled dormer heads with timber spike finials above the first-floor windows. The north elevation has a broad bowed bay at the center and a window to the left. The east elevation is gabled and blank, while the west elevation is attached to lower outbuildings. The cottage has 4-pane glazing in sash and case windows, coped skews, painted brick gablehead stacks, and is covered with purple-grey slates.

The Bothy is a single-storey structure that consists of a 6-bay pair of former cottages. The south elevation features doors in the penultimate bay to the left and in the outer right bay, with windows in the remaining bays. A low rubble wall is attached to the right. The east elevation has a window to the left, while the north elevation has a further gabled range attached. The Bothy also has 12-pane glazing in sash and case windows, coped skews, brick stacks at the gablehead and mutual, and is similarly covered with purple-grey slates.
