Just 12 miles northeast of Southampton, the city of Winchester in Hampshire is perhaps best-known for Winchester Cathedral, which was completed in the year 1093 and is considered one of the grandest Gothic cathedrals built in all of Europe. At 558 feet long, it is the longest Gothic cathedral in the world and in overall area it ranks as one of the world`s largest. Winchester is also well-known as a base for travelers who want to explore the South Downs National Park, which is almost immediately to the city`s east. Other noteworthy sights in Winchester include The Great Hall, the only portion of the 11th-century Winchester Castle left standing; and The City Mill, which has milled corn and flour for centuries.
