The town is above the river, and set away from the parks. Until the 1970s, it had many shops. However accidents occurred from increased traffic close to winding bends and narrow pavements. Since then the central streets have been pedestrianised or partly blocked off, leading to a decline in the number of pedestrians and shop closures in favour of out-of-town supermarkets. The construction of the Swan Centre and its supermarket, brought some revitalisation. In 2002, the high street was voted one of the worst in the United Kingdom in a BBC poll.
