Irkutsk is capital of the Russian province of Irkutsk Oblast in Eastern Siberia. In the early nineteenth century, many Russian artists, officers and nobles were sent into exile to Siberia for their part in the Decembrist revolt against Tsar Nicholas I. Irkutsk became the major center of intellectual and social life for these exiles, and much of the city's cultural heritage comes from them; also, many of their wooden houses, adorned with ornate, hand-carved decorations, survive today in stark contrast with the standard Soviet apartment blocks that surround them.
