After the Decemberist Revolt of 1825, many Russian artists, officers, and nobles were sent into exile to Siberia for their part in the revolt against Tsar Nicholas I and in the late 1800s, 30% of the population of the city were exiles. Irkutsk became the major centre of intellectual and social life for these exiles, and much of the city's cultural heritage is a result of these exiles. Many of their wooden houses, adorned with ornate, hand-carved decorations, survive today in stark contrast with the surrounding Soviet apartment blocks. Around 1900, the city was nicknamed the "Paris of Siberia" due to its wide streets and ornate, continental architecture but travellers today will find little resemblance with Paris.
