Over the centuries, many cultures have added their mark to this prized piece of land. Today, you can experience those influences firsthand by exploring Istanbul’s mahalles (neighborhoods). From the holy sites of Sultanahmet and the 19th-century European elegance of Beyoğlu to the high fashion of Nişantaşı, the vibrant café society of Kadıköy and the football-loving streets of Beşiktaş, it’s easy to see why travelers say that Istanbul isn’t just one city, but many cities within one.

Having survived the Mongol Empire, WWII, and Chernobyl, Kyiv is the proud capital of Ukraine. Filled with theaters, museums, religious sites, modern buildings and ancient ruins, the city of Kyiv is the center of Ukrainian culture. The Monastery of the Caves, founded in 1015, and Saint Sophia Cathedral, founded in 1037, are both World Heritage Sites. The Museum of the Great Patriotic War, topped by the massive Motherland Statue, provides gorgeous views of the city below.

Tallinn's atmospheric Old Town is an enthralling hodgepodge of medieval streets and spires. It's a small city, and the tourist areas are safe and easily explored on foot. Buy a Tallinn Card if intending to use buses, trolleys or trams. For a look into Tallinn's past, visit Rocca-al-Mare Open Air Museum's typical rural Estonian taverns, windmills and watermills, see the onion-domed 1900 cathedral or join the bustle in historic Town Hall Square. St. Olav's spire was once the tallest in the world.

Independent Black Forest locales dating back to medieval times, in 1971, Titisee and Neustadt (along with Rudenberg) banded together to form Titisee-Neustadt. (A few years later, nearby towns Langenordnach, Schwärzenbach and Waldau also joined the union.) Long known as a spa town, Titisee sits on the banks of the lake of the same name. Legend says the name came from Roman Emperor Titus, who was so taken by its beauty that he named it after himself. The area is great for hiking and winter sports.

Designed by renowned French architect Jean Le Couteur, the resort town of Cap-d'Agde sprung up in the 1960s. It remains a popular spot among Mediterranean sunseekers, with multiple sandy beaches, islands, and amusement parks set around a natural lagoon.

Harrogate is also known as "The English Spa." For centuries, visitors have flocked to the mineral hot springs. Today, those springs still soothe the body while the placid RHS Harlow Carr Gardens and Yorkshire Dales national park stimulate the soul. Tea rooms, architecture, and art galleries are the main pastimes in this pleasant town.  With four rail stations for easy transport, travelers can board trains running between Harrogate and York, Leeds, Knaresborough, and London.

Known as the Home of Golf, pretty St. Andrews appeals to even those with no interest in the game. Set on a wide bay, the town is dotted with medieval ruins, stately architecture, and—thanks to its large student population—plenty of cozy pubs.
