LOCATION, AREA, BOUNDARIES, LANDFORM, SETTING Miller Park is situated c 1km south of Preston town centre, on land occupying c 3ha which slopes southwards down to the River Ribble. The river forms the site's southern boundary. The east and west boundaries are formed by railway embankments. The northern boundary is formed by a stone wall which has balustrading in front of the former Park Hotel, now used as the County Council Offices, which overlooks the park. The railway embankment on the east side separates Miller Park from Avenham Park (qv), which was also designed by Milner. The two parks are linked by bridges at each end of the embankment and continuity between the two sites is given by the views along the shared riverside walk. On the south side of the River Ribble there are playing fields with open land beyond; these form part of the setting and can be seen in views looking south from the park.
ENTRANCES AND APPROACHES There are four entrances to the park, all leading beneath bridges at each end of the railway embankments which form the east and west boundaries of the site. The principal entrance is from West Cliff. At the southern end of this street there is a pair of brick gate piers with stone carvings of the Agnus Dei (from the town's coat of arms) in gabled canopies. Immediately to the west of the gateway there is a brick-built gabled lodge. A tree-lined path runs south-eastwards to the railway embankment where it divides; ahead to the east there is an entrance to the park beneath a railway bridge with a decorative cast-iron parapet. Another path leads off to the south along the line of the embankment which is planted with trees and lined with rockwork. This leads beneath a sandstone railway bridge and joins with another path leading into the park from Riverside.
The eastern railway embankment, dividing Miller Park from Avenham Park, has a bridge at each end forming entrances from Avenham Park. The northern bridge (c 1846, listed Grade II) is of stone with a stone parapet. The southern bridge (c 1846, listed Grade II) carries the railway over the riverside walk and is linked with a viaduct which carried the railway over the Ribble.
GARDENS AND PLEASURE GROUNDS The central part of Miller Park is strongly formal in character and there are less formal areas at the north-east and north-west corners of the site.
Three terraces have been laid out on sloping land on the north side of the site. The central terrace, which forms the main axis and focus of the park, consists of a broad path which has on its south side, at the edge of the terrace, a range of plinths supporting ornamental urns (all listed Grade II). In the centre of the terrace on the northern side of the path there is a statue of the fourteenth Earl of Derby (Matthew Noble 1873, listed Grade II), which is known as the Derby Monument. In front of this a balustraded double staircase leads down to the terrace below. From this point the stair continues as a single, wide flight of steps down to formal lawns and a circular pool with an ornate fountain (c 1865, listed Grade II) which is aligned with the stair and situated c 80m south of the Derby Monument. Some 10m south of this there is a garden with formal beds surrounded by a beech hedge in which is situated a bandstand. This garden was created and the bandstand introduced in the late C20.
The land slopes up steeply to the north of the Derby Monument. Rustic steps lead up on either side of the statue and join to form a single flight of steps up the slope, mirroring in an informal manner the formal staircase on the terraces below.
There is an area of rockwork consisting of large, naturalistically arranged stone slabs and boulders along the western side of the site against the railway embankment. A path leads off south-westwards from the northern railway bridge entrance, through a rockwork arch and on through rockwork and pools. The path emerges from the rockwork to skirt planting on the railway embankment and continues southwards to join with the riverside walk. An area east of the rockwork, c 150m south-west of the Derby Monument, has been laid out with formal beds around a spiral-shaped path with a sundial at the centre. This arrangement conforms with the layout shown on the 1893 OS map.
There is another, less extensive area of rockwork which extends c 50m southwards along the embankment from the northern entrance into Avenham Park. Here there are stone steps leading up to a seat set into the embankment and paths leading through a rockwork arch. Thick planting screens the remainder of the embankment.
The park also contains examples of Pulhamite rockwork, designed by James Pulham, including a waterfall, cliffs, a rocky pond and a drinking fountain.
