The park was originally part of the grounds of Radnor House, built in the early 18th century for John Robartes, 4th Earl of Radnor.
The ornate stone alcove surviving in the gardens was salvaged from the original Radnor House estate after the building was bombed in 1940.
A commemorative plaque honors Alexander Pope, the poet who lived in a nearby villa, highlighting the area's historical association with 18th-century literary figures.
The park hosts a public riverside terrace that sits on a bend in the Thames, offering clear views of the river's path toward Teddington Lock.
During low tide, the riverbank reveals a stretch of foreshore that is frequently used for mudlarking and archaeological exploration.
Radnor Gardens is a Victorian-era riverside park located directly on the banks of the River Thames in Twickenham. The park occupies land once associated with several 18th-century villas, including Radnor House, which was destroyed by fire during the Second World War. It features a formal rose garden, a dedicated children's play area, and an active riverside promenade. The park provides public access to the water's edge, including a small beach area exposed at low tide. Notable historical elements include the ornate stone alcove, a remnant of the original villa grounds. The park is managed by the London Borough of Richmond upon Thames. It serves as a local community hub and provides a direct viewpoint for boat traffic on the Thames.
The interior of the historic stone alcove looking out toward the river provides a framed, classic view.
Check the tide charts before visiting if you plan to explore the foreshore or walk along the water's edge.
Bring a picnic blanket as the expansive lawns are the primary seating area for visitors.
The riverside path is narrow; be mindful of cyclists and runners who use the route as a transit corridor.
Do not attempt to walk along the river edge when the tide is high, as the path can become submerged or slippery.
No barbecues or open fires; keep dogs under control, especially near the riverbank and children's play area.
