The city is large and very important port with deep historical background. Samara is located at the confluence of two rivers: here the Samara River flows into the Volga River. Well-developed cities of the past were often built where rivers merge, because it was easier to protect them and to trade successfully. Samara is a fusion of old trade town with well-preserved buildings, the features of Soviet period and the ones of present time. Historical center of Samara has remarkable architecture: Samara's Gorky Drama Theater is a unique teremok-building in Russian style; the House of merchant Kurlina is an example of Samara’s art nouveau; Lutheran Church of St. George and Roman Catholic Church are of gothic style.
