LAVENHAM, eight miles northeast of Sudbury, was once a centre of the region’s wool trade and is now one of the most visited villages in Suffolk, thanks to its unrivalled ensemble of perfectly preserved half-timbered houses. In outward appearance at least, the whole place has changed little since the demise of the wool industry, owing in part to a zealous local preservation society, which has carefully maintained the village’s antique appearance. Lavenham is at its most beguiling in the triangular Market Place, an airy spot flanked by pastel-painted, medieval dwellings whose beams have been warped into all sorts of wonky angles by the passing of the years.
