Sintra is like the one-stop shop for castle lovers, with not one, not two, but three gorgeous castles. This medieval stronghold town is so beautiful it was called Glorious Eden by the British poet Lord Byron. Pictured here: Pena Palace.

Set on the Atlantic Coast of Cape Breton Island in Nova Scotia, Louisbourg began life peacefully enough in 1713 as a fishing port. But when the Anglo-French struggle for Canada began a few years later, the French colonists started building a series of stone city walls, transforming the sleepy village into a massive fortress.

The city of Rhodes in Greece is comprised of a unique mix of Islamic minarets, European buttresses, and pebble-stone mosaic pavements. Within the city's thick sandstone walls, you'll find the Palace of the Grand Masters, built by crusading knights in the 14th century, alongside a candy-striped mosque, a Byzantine museum, and a Muslim library.
Today, many of Rhodes's Greek residents are shopkeepers who sell honey produced by the island's many beekeepers; others craft necklaces and souvenirs made from shells cast ashore.
Jaisalmer Fort rises nearly 25 stories off the flat, seemingly endless floor of the Great Thar Desert in western Rajasthan in India. Its 99 bastions were constructed out of yellow bentonite sandstone—giving it the appearance of a massive, intricately carved, sand castle.

Rajput warriors and Jain merchants founded Jaisalmer, the so-called Golden City, in 1156 and—unlike many fortress communities—it was never abandoned.
Founded in 1593 as a stronghold of the Venetian Republic, Palmanova, Italy was built in a unique, 18-sided octadecagon shape. When viewed from above, the fortress community looks like a delicately made paper snowflake, with streets radiating out of the structure like sunbeams.
Tucked into a valley with a lagoon running into the Adriatic Sea, the land surrounding Palmanova yields high-quality Chardonnay, while the local waters are stocked with mullet, sea bass, and other delicious fish. In town, look out for the symbol of a leafy bough, or a frasca, hanging outside of restaurants to pinpoint ones serving regionally sourced food.

Castles in Korea resemble elaborate pagoda-type buildings, surrounded by thick stone walls. The best preserved of these is in the town of Naganeupseong, a three-square-mile gem nestled in a valley beneath some low-lying mountains near the southwestern city of Suncheon.

As remarkable as it is unpronounceable, Naganeupseong (nagan means "safe and pleasant" and seong means "castle") was built in 1397 and still has a couple hundred residents living in its hub of 30 or so thatched-roof adobe houses.
Segovia Castle, in the town of Segovia, rises out on a rocky crag above the confluence of the Eresma and Clamores rivers, near the Guadarrama Mountains in Spain.
