Ljubljana is the capital and largest city of Slovenia. It is the cultural, educational, economic, political and administrative centre of the country. The symbol of the city is the Ljubljana Dragon. It is depicted on the top of the tower of Ljubljana Castle in the Ljubljana coat of arms and on the Ljubljanica-crossing Dragon Bridge (Zmajski most). It symbolises power, courage, and greatness.
Around 2000 BC, the Ljubljana Marshes in the immediate vicinity of Ljubljana were settled by people living in pile dwellings. Prehistoric pile dwellings and the oldest wooden wheel in the world are among the most notable archeological findings from the marshland. These lake-dwelling people lived through hunting, fishing and primitive agriculture. To get around the marshes, they used dugout canoes made by cutting out the inside of tree trunks. Their archaeological remains, nowadays in the Municipality of Ig, have been designated a UNESCO World Heritage Site since June 2011, in the common nomination of six Alpine states.
The city's architecture is a mix of architectural styles. Despite the appearance of large buildings, especially at the city's edge, Ljubljana's historic centre remains intact. Although the oldest architecture has been preserved from the Roman period, Ljubljana's downtown got its outline in the Middle Ages. After the 1511 earthquake, it was rebuilt in the Baroque style following Italian, particularly Venetian, models.
