The third largest city on Crete, Rethymno came to life during the Venetian era and is home to many historic buildings, notably hilltop Rethymno's Fortress, which dominates the city's skyline.

During spring, the Rethymno Carnival takes place, which is a century-old celebration that has become an institution famous throughout the country.

Tivoli park was once the grounds of a castle barely two kilometres from the historic centre of Mechelen. These days you can enjoy a quiet stroll here across the large expanses of grass, past ancient trees, a highly-scented rose garden, a herb garden and other delightful nooks. Now pure white again, in 1990 the famous Belgian artist Jan Fabre wrapped the castle in sheets of paper covered with ballpoint lines for which 150,000 blue pens were required! Since 1991 the mansion has housed a catering establishment specializing in parties, seminars and the like. Drinks, snacks and lunches are served to the general public in the adjoining orangery. Small children will love meeting a whole variety of farm animals on the children's farm. Other attractions include the large bee colony and the educational nature trail where signs draw your attention to aspects of the park's history, fauna and flora.

Saarbrücken has plenty to offer to the lovers of architecture, and one unmissable landmark is the city's town hall, built at the turn of the 20th century in neo-Gothic style and designed by Georg Von Hauberrisser, whose works also include the town hall in Munich.
