7Monemvasia, Peloponnese

Dubbed the “Gibraltar of the East,” Monemvasia is a hidden gem tucked away on a rocky island off the southeastern coast of the Peloponnese. Accessible only by a narrow causeway, this medieval fortress town is a labyrinth of cobbled streets, Byzantine churches, and Venetian mansions. Visitors can explore the ancient walls, climb to the top of the fortress for panoramic views of the sea, and wander through the picturesque alleys lined with artisan shops and tavernas.
