As one of the most famous complexes of historic structures in the world, it stands to reason that the Tower of London would have a plethora of websites dedicated to exploring its development and rather crucial role in English history. Begun by William the Conquerer, the castle has been improved and added upon numerous times over the past 900 years, and now includes dozens of smaller structures within its walls. Developed by staff members at Knight International, this site is a real treat for those seeking to learn more about this historic site, or those who might be planning a visit in the future. The site contains approximately a dozen different areas of interest, ranging from a fine virtual tour of the grounds, a section devoted to the omnipresent ravens and, of course, a copious amount of materials on the Crown Jewels.
