I've just come across a really nice video of medieval Lincoln, thanks to Medievalists.net. It's on YouTube, and it is a virtual tour of the city, which was once one of the largest and wealthiest towns in England. As you will see when you view the video, there is plenty to delight the dedicated fan of medieval times. There are many old buildings, a castle, and a cathedral, and all of these were started or built in the 11th or 12th centuries. There are also several good examples of what are known as "cruck" houses. Many people would call them "half-timbered", and in the US, imitation ones are called "Tudor", though the style itself is much older. Interestingly, Lincoln Cathedral's "Romanesque" style(it was built in the late 11th century and added on in subsequent centuries, has been copied in many places. An important academic library in the city where I live(and in which I delved for information for my Great Medieval Science Fiction Masterpiece -- as well as some other subjects), was originally built in an imitation of this style, though I have no idea whether or not it was built in imitation of Lincoln Cathedral.
