If you're looking for a specific movie or documentary about Viking sieges, I recommend checking out streaming platforms like Netflix, Amazon Prime Video, or YouTube, which often host a wide range of historical documentaries and movies.
Instead, I'd like to provide you with some interesting facts and possibly a recommended movie or documentary about Viking sieges:
During the Viking Age (793-1066 CE), Viking warriors, known for their lightning-fast raids and impressive naval power, besieged numerous towns, monasteries, and fortresses across Europe. These sieges were often brutal and bloody, with the Vikings employing various tactics, such as surprise attacks, blockade, and siege engines.
