The National Botanic Gardens of Wales spreads out into 500-plus acres at Llanarthne in the Carmarthenshire countryside and boasts a spectacular structure designed by Norman Foster: the largest single-span glasshouse in the world.
In this verdant setting Brita Rogers of Derwen Fairs holds her flagship antiques vintage and retro fairs, with the first this year running on Saturday and Sunday, January 26-27.
It involves 60 standholders inside the glasshouse, many specialising in pieces with a Welsh flavour, and around 40 more in marquees dotted around the courtyard and in nearby buildings.
