Fodor's Expert Review Llanerchaeron

This late 18th-century Welsh gentry estate in the Aeron Valley, 17 miles south of Aberystwyth, is a superb example of the early work of John Nash (1752–1835). Nash was the leading architect of the Regency period and the designer of London's Marble Arch and Buckingham Palace. The estate survived with few changes until recently; it is a self-contained world with a farmyard, a brewery, and a café. The walled gardens are particularly beautiful.
