This elegant little neo-classic temple, listed as Grade II*, was erected some 40 years after Nelson's visit as a tribute to his memory following the enlargement of the original garden. It enshrines parts of the armchair he used/graced at a grand banquet (at the Beaufort Hotel) in his honour and contains a (later) plaque commemorating the event.

The Tuscan Doric design shows some influence of Sir John Soane and has been attributed to the Monmouth architect George Maddox who worked briefly in his office.

Now carefully restored by conservation architects, it has been finished in colours researched from the original paint scheme of HMS Victory.
