Zagreb is an important tourist centre, not only in terms of passengers travelling from Western and Central Europe to the Adriatic Sea, but also as a travel destination itself. Zagreb has numerous cultural and historical monuments, museums and galleries, but also as a vibrant destination with a variety of modern shops, quality restaurants and sports/recreational facilities. It is a major centre of congress tourism, hosting a number of business events and trade fairs.  The historical part of the city to the north of Ban Jelačić Square is comprised of the Upper Town and Kaptol, a medieval urban complex of churches, palaces, museums, galleries and government buildings that are exceptionally popular with tourists on sightseeing tours. The old town's streets and squares can be reached on foot, starting from Jelačić Square, the central part and the heart of Zagreb, or by a funicular on nearby Tomićeva Street. Tkalčićeva ulica is a winding street in the old town that features many very popular cafés and is a popular place for people-watching, particularly among the younger generations.
