Grosvenor & Hilbert Park: A Brief History

Grosvenor Recreation Ground was opened in 1889 and was the first public park in Tunbridge Wells. There is a beautiful lake with unusual 'Dripping Wells', a hundred-year-old bowling green, a brand-new playground and a wetland area. It was the brainchild of the town's first Mayor, John Stone-Wigg, who paid for famous landscape designer Robert Marnock to plan the layout.

Hilbert Recreation Ground was added in the 1930s and contains the playing fields, an historic Kentish oast house, two ancient woodlands, a skate park and a thriving community orchard. Formerly part of a small farm, the 26 acres (10.5ha) of land was donated by Councillor Edward Jeffery Strange and named after his mother Lydia Hilbert.

Together, they form a park with diverse habitats and a range of amenities for all ages - truly a People's Park!

Just For Kids

Can you see the steps to nowhere? They are called 'Grosvenor Rocks'. If you look closely, you will see some pictures and words scratched into the rocks. Can you find the bee?

Grosvenor Rocks: History

Where you are standing now was once the industrial heart of Tunbridge Wells. Initially the area was a quarry, where the stone was used for buildings such as Trinity Church and the other Decimus Burton houses around Calverley Grounds. The quarry later became three reservoirs and a waterworks, utilising the Jackwood Spring that ran through the area.

When the first trains arrived at Tunbridge Wells in 1845, they stopped at Jackwood, which was just beyond Grosvenor Bridge. A year later, after the tunnel was completed this became the Goods Station. In the days before road haulage, most goods were brought in by train, so the area was incredibly busy. There were numerous sidings and two goods sheds, where goods were unloaded before being carted away with horse-drawn transport.

Some sidings led into the Medway Coal Wharf, which dealt with much of the town's coal, located between Marnock Lake and St James's Road (it's now flats). There were sidings into the Council-run Stone Yard, where rocks quarried in Sevenoaks were broken up and used to maintain the roads.

More sidings were built for direct coal delivery when the Council-run Electric Light Works opened in 1875. The works used water from Jackwood Spring, which was heated in coal-fired boilers to make steam, which powered turbines to generate electricity. The townspeople gradually converted from gas lighting to electric, so the renamed Electricity Works kept expanding.

The Baltic Saw Mills were also nearby: first in Commercial Road, then in Goods Station Road.

The area was constantly busy and noisy, and the air was polluted by smoke from steam trains and the Electric Light Works, as well as dust from the Coal Wharf, Stone Yard and the roads. From the 1870s residents and traders began requesting a road bridge at the Goods Station. Funded by a Local Government Board loan of £10,000, Grosvenor Bridge opened in March 1883. There were three wrought iron spans, supported on red brick piers. Arches under the bridge became the town mortuary and local council storage.

From the 1930s the area gradually became less important. Volumes of rail freight declined, as roads improved, and the cost of road haulage reduced. Medway Coal Wharf closed during World War II, becoming an additional Council Yard.

The railways were nationalised in 1947, but changes to the freight service failed to stop the move to transporting goods by road. The Goods Station closed in 1980, with the buildings demolished in 2007 as the area was opened up to residential development.

The UK electrical power industry was nationalised in 1947, when over 600 local power companies were merged into 12 area boards. South Eastern Electricity Board (SEEBOARD) took over Tunbridge Wells Electrical Works. In March 1969 Mayor Kenneth Morrison turned off the turbines at the electricity works for the last time, ending 74 years of operation. The 180 foot power station chimney stack was demolished brick by brick in 1970. The engine house (formerly the Trident Trailers building) remained until it was demolished in 2023 by UK Power Network.

The original Grosvenor Bridge was demolished and rebuilt in 1968, after metal fatigue was found in 1965. The wrought iron bridge was not strong enough for heavier vehicles and increased traffic volumes. The brick arches at the Quarry Road end remain and are now bicycle parking for the nearby flats.

There's just one trace of the industrial area left: the Baltic Saw Mills building can be found on Goods Station Road, now occupied by Southpaw.

Grosvenor Rocks: Art

Look across the 'grassy knoll' and you will see an unusual structure - this is Grosvenor Rocks. Installed in 2013 by 'We Made That' it celebrates the quarry that was originally situated in this area.

This is part of a series of art installations along the cycle path. It's a reminder that the area was formerly a quarry, supplying the stone for the early expansion of the town. Nine pieces of sandstone were selected from a quarry in West Hoathly. In April 2013, local people wrote and drew on the stone. These contributions were permanently carved into the stone by letter cutter Bridget Powell and apprentice stonemason Amelia Morrison.

Street art walls

Underneath Grosvenor Bridge the walls have featured murals by Humor, a Tunbridge Wells-based street artist gaining increasing recognition. In addition, they are used by local street artists to express themselves.

What Next: Marnock Lake

The next stop will be Marnock Lake, step into the park, turn left and follow the path down to the 'Lake'.
