Rovaniemi (Finnish: [ˈroʋɑniemi] (listen)) is a city and municipality of Finland. It is the administrative capital and commercial centre of Finland's northernmost province, Lapland. It is situated about 6 kilometres (4 miles) south of the Arctic Circle and is between the hills of Ounasvaara and Korkalovaara, at the confluence of the river Kemijoki and its tributary, the Ounasjoki. The city and the surrounding Rovaniemen maalaiskunta (Rural municipality of Rovaniemi) were consolidated into a single entity on 1 January 2006.

The resulting city of Rovaniemi is considered the largest city in all of Europe by land area, because the defined limits of the city proper extend far beyond the actual urban area.Rovaniemi municipality has an approximate population of 63,000. The urban area of Rovaniemi has a population of 53 361, in an area of 5,977 km2 (2,308 sq mi). Rovaniemi is a unilingual Finnish-speaking municipality and, uncommonly for larger Finnish towns, it is also known by its Finnish name and spelling in the Swedish language.

In geology, a boulder is a rock fragment with size greater than 256 millimetres (10.1 in) in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive. In common usage, a boulder is too large for a person to move. Smaller boulders are usually just called rocks (American English) or stones (In British English a rock is larger than a boulder). The word boulder is short for boulder stone, from Middle English bulderston or Swedish bullersten.In places covered by ice sheets during Ice Ages, such as Scandinavia, northern North America, and Siberia, glacial erratics are common. Erratics are boulders picked up by ice sheets during their advance, and deposited when they melt.

They are called "erratic" because they typically are of a different rock type than the bedrock on which they are deposited. One of them is used as the pedestal of the Bronze Horseman in Saint Petersburg, Russia. Some noted rock formations involve giant boulders exposed by erosion, such as the Devil's Marbles in Australia's Northern Territory, the Horeke basalts in New Zealand, where an entire valley contains only boulders, and The Baths on the island of Virgin Gorda in the British Virgin Islands. Boulder-sized clasts are found in some sedimentary rocks, such as coarse conglomerate and boulder clay. The climbing of large boulders is called bouldering.
