What more atmospheric place to celebrate today"s summer solstice than ancient Glastonbury in Somerset, England? Spend the longest day of the year exploring the town, which is swaddled in myth and history. Pagans and Christians alike have worshipped here through the ages, and both groups still do today. Glastonbury Tor is the striking hill on the horizon, and the lonely tower is the last vestige of the 14th-century church of St Michael, which was built to replace a wooden church toppled by an earthquake in 1275.
