A drawbridge is a type of bridge that can be lifted up or lowered down to let boats or ships pass underneath it. They are often found over rivers or canals, and are used to allow boats with tall masts to pass through without having to go around or under the bridge. Some drawbridges are also used for defense purposes, as they can be raised to prevent enemies from crossing the bridge. Nowadays, drawbridges are mostly used as a tourist attraction or for aesthetic purposes.
