Zagreb is the capital and the largest city of Croatia, situated in the northwest of the country along the Sava River. As a vibrant hub of culture, history, and economics, Zagreb is a city where the contemporary and the historic blend seamlessly. The city's Upper Town (Gornji Grad) is known for its well-preserved medieval street patterns and architecture, including the iconic St. Mark's Church with its multicolored tile roof. The Lower Town (Donji Grad) features grandiose Austro-Hungarian buildings, bustling squares such as Ban Jelačić Square, and numerous parks and gardens, contributing to Zagreb's reputation as a green city. Zagreb is also a city of museums, with more per capita than any other city in the world, showcasing its rich heritage and artistic endeavors. The city's street life is vibrant, with numerous cafes, restaurants, and shops, reflecting the laid-back lifestyle of its residents. Cultural events, festivals, and open-air concerts are common, particularly during the summer months, when the city's streets and squares become lively stages for various performances. Despite its bustling urban atmosphere, Zagreb is close to natural escapes, such as Mount Medvednica to the north, which provides a quick retreat for hiking and skiing.
