Well, Ljubljana has a long history. There is evidence of ancient tribes occupying the area long before the Romans put up a settlement called Emona. In 12th century the name Luvigana first appears and in 13th century it is granted city rights.
Since the town is situated in a seismically active area, it has been affected by earthquakes throughout its history. After an earthquake in 1511 it was rebuilt in Renaissance style and in the 17th century Baroque architecture appeared.
Another earthquake hit the city in 1895, and destroyed some 10% of the buildings. Large parts were reconstructed in Art Nouveau style.
So, today the old city is a mixture of different styles and, apart from being the capital of Slovenia, it is also a strong cultural centre.
