Smolensk is a city and the administrative center of Smolensk Oblast, Russia, located on the Dnieper River, 360 kilometers (220 mi) west-southwest of Moscow. The city has been destroyed several times throughout its long history because it was on the invasion routes of various empires. Smolensk is known for its electronics, textiles, food processing, and diamond faceting industries. On April 10, 2010, a Tu-154 military jet carrying Polish president Lech Kaczyński, his wife, and many notable political and military figures crashed in a wooded area near Smolensk while approaching the local military airport. All ninety-six passengers died immediately on impact. The purpose of the visit was to commemorate the 70th anniversary of the Katyn massacre.
The city is located in European Russia on the banks of the upper Dnieper River, which crosses the city within the Smolensk Upland, which is the western part of the Smolensk–Moscow Upland. The Dnieper River flows through the city from east to west and divides it into two parts: the northern (Zadneprove) and southern (center). Within the city and its surroundings the river takes in several small tributaries. In the valleys are stretched streets, high ridges, hills, and headlands form the mountain. Smolensk is situated on seven hills (mountains). The old part of the city occupies the high, rugged left (south) bank of the Dnieper River. The area features undulating terrain, with a large number of tributaries, creeks and ravines.
Owing to its long and rich history, Smolensk is home to many examples of Russian architecture ranging from the Kievan Rus period to post-WWII Stalinist architecture. Although the city was destroyed several times over, many historically and culturally significant buildings still remain, including a large number of churches and cathedrals. The most famous of these are the Cathedral of the Assumption, the Immaculate Conception Church, and the Church of St. Michael the Archangel, which is one of the few structures from before the Mongol invasion remaining in Russia.
The Smolensk Kremlin, built at the end of the 16th century during the reign of Tsars Fyodor I Ioannovich and Boris Godunov, under the supervision of the architect Fyodor Kon, is one of the greatest achievement of Russian medieval architecture and military engineering.
