Long before you enter Salisbury, the spire of its cathedral comes into view -- just as John Constable captured it on canvas. The 121m (404-ft.) pinnacle of the Early English and Gothic cathedral is the tallest in England.Salisbury, or New Sarum, lies in the valley of the River Avon. Filled with Tudor inns and tearooms, it is the only true city in Wiltshire. It's an excellent base for visitors anxious to explore Stonehenge or Avebury, who, unfortunately, tend to visit the cathedral and then rush on their way. But the old market town is an interesting destination on its own, and if you choose to linger here for a day or two, you find that its pub-to-citizen ratio is perhaps the highest in the country.
