Here's what we know:
* Filming Locations: The various Hornblower adaptations were filmed in a variety of locations, including:
* Malta (for many of the seafaring scenes)
* The UK (including various locations in England and Scotland, but not specifically Rye)
* Spain
* Croatia
* Romania
* Hungary
* The Czech Republic
* Rye's History: Rye is a charming coastal town with a long maritime history. It played a significant role in English naval history, making it an ideal setting for a Hornblower story. However, it's important to note that filming locations are chosen for practical reasons, such as availability, budget, and aesthetics.
* No Specific Mentions: No official sources, cast interviews, or behind-the-scenes information explicitly mention Rye as a filming location for any of the Hornblower adaptations.
While Rye's history and setting are perfect for a Hornblower story, there's no evidence that any part of the series was filmed there.
