The Naval Temple is believed to be the only monument in Britain dedicated to the British Navy as it existed during the French Revolutionary Wars.
The Round House was built specifically for the Monmouth Pic-Nic Club, a group of 20 gentlemen who met there for dinners.
Admiral Horatio Nelson visited the site in 1802 and was entertained at the Round House during his tour of the Wye Valley.
The monument's architecture reflects the picturesque movement popular in late 18th-century landscape gardening.
The site offers views extending as far as the Brecon Beacons on clear days.
The Kymin is an 18th-century pleasure ground located on a prominent hilltop overlooking Monmouth and the Wye Valley. Its most iconic feature is the Round House, a white circular banqueting house built in 1794 by the Monmouth Pic-Nic Club. Adjacent to the Round House stands the Naval Temple, a monument erected in 1800 to commemorate British naval victories, featuring busts of celebrated admirals. The site sits at an elevation of approximately 800 feet, providing panoramic views across the border of England and Wales. The grounds were designed as a destination for the local gentry to host social gatherings and enjoy landscape views. The site is managed by the National Trust and is maintained primarily for its historical architecture and scenic outlook. Visitors can explore the grounds independently and walk the surrounding woodland trails.

Bring a pair of binoculars to make the most of the extensive views across the Wye Valley.
The walk to the summit involves a steep incline, so wear sturdy footwear appropriate for hilly terrain.
Check local weather forecasts before visiting, as the hilltop is highly exposed to wind and rain.
Do not attempt to drive a large vehicle up the narrow, winding Kymin Road; use the designated parking areas provided by the National Trust.
The grounds are generally open year-round, but specific interior access to the Round House may be seasonal or subject to volunteer availability.
Dress for changeable weather and remain on marked footpaths to preserve the surrounding grassland.
