Question: The Battle of Vilnius was the first time a foreign power managed to capture a group of cultural, and historic structures on the left bank of what river?
Context: The Podhajsky-Jansa Farmstead District is an agricultural historic district located southwest of Ely, Iowa, United States.  It was listed on the National Register of Historic Places in 2000.  At the time of its nomination it consisted of 12 resources, which included five contributing buildings, four contributing structures, and three non-contributing structures.  The historic buildings include two small side gabled houses (c. 1860s-1880s); a two-story, frame, American Foursquare house (1910s or 1920s); a gabled barn that was moved here from another farm (1890s-early 1900s); and a feeder barn (c. 1912).  One of two corncribs (1933), a hog house (early 1900s), and a chicken house (early 1900s) are the historic structures.  Another corncrib and a couple of metal sheds from the mid to late 20th century are the non-contributing structures. The Historic Cities Programme (HCP) of the Aga Khan Trust for Culture (AKTC)] promotes the conservation and re-use of buildings and public spaces in historic cities of the Muslim World.  HCP undertakes the restoration and rehabilitation of historic structures and public spaces in ways that can spur social, economic and cultural development.  Individual projects go beyond technical restoration to address the questions of the social and environmental context, adaptive reuse, institutional sustainability and training.  In several countries, local Aga Khan Cultural Service companies have been formed to implement projects under the supervision of the HCSP headquarters in Geneva. Hakari River (Azerbaijani: "Həkəri" ) is the left tributary of the Araz in Azerbaijan.  The river is 128 km long and flows through Qubadli District and Zangilan District.  Several populated places are along the river, like Aganli (on the left bank), Alibayli (on the right bank), Mammadbayli (on the left bank) and Yenikend (on the right bank).  The Armenia–Azerbaijan border runs near the river. Kalnai Park (Lithuanian: "Kalnų parkas" , literally: "Park of Hills") is a 24.5 ha park between the left bank of the Neris River and right bank of the Vilnia River in Vilnius, Lithuania.  It lies within the Vilnius Old Town elderate near Gediminas Hill and Gediminas Tower, and is part of the State Cultural Reserve of Vilnius Castles, established in 1997.  The park hosts various events, including concerts, political rallies, and sporting competitions.  Its name reflects the presence of four prominent hills ("kalnai"): Crooked Hill, Table Hill, Bekes Hill, and the Hill of Gediminas's Grave. The National Hall Historic District is a 3 acre historic district in Westport, Connecticut that was listed on the National Register of Historic Places in 1984.  The district encompasses a historic commercial center of the town, located on the west bank of the Saugatuck River where the Boston Post Road crosses the river.  It includes eleven historic structures, most of which historically had some sort of commercial function.  There are a few residences, and one civic structure, the wood-frame Vigilante Fire House on Wilton Road.  The centerpiece of the district is the large National Hall building, an 1873 three-story Italianate structure that visually dominates the junction of the Post Road with Wilton Road and Reservoir Road.  The area's first period of development was in the early 19th century, a period from which five buildings survive. Established in 1994, the Cane River Creole National Historical Park serves to preserve the resources and cultural landscapes of the Cane River region.  Located along the Cane River Lake, the park is approximately 63 acres and includes two French Creole cotton plantations, Oakland and Magnolia.  Both plantations reflect completeness in their historic settings, including landscapes, outbuildings, structures, furnishings, and artifacts; and they are the most intact French Creole cotton plantations in the United States.  In total, 65 historic structures and over a million artifacts enhance the National Park Service mission as it strives to tell the story of the evolution of plantation agriculture through the perspective of the land owners, enslaved workers, overseers, skilled workers, and tenant farmers who resided along the Cane River for over two hundred years. The Vilnius Castle Complex (Lithuanian: "Vilniaus pilių kompleksas" or "Vilniaus pilys" ) is a group of cultural, and historic structures on the left bank of the Neris River, near its confluence with the Vilnia River, in Vilnius, Lithuania.  The buildings, which evolved between the 10th and 18th centuries, were one of Lithuania's major defensive structures. Antakalnis (lit.  'the place on hills') is an eldership in the Vilnius city municipality, Lithuania.  Antakalnis is one of the oldest historical suburbs of Vilnius City.  It is located in the eastern section of Vilnius, along the left bank of the Neris River, with the river running along the whole western side of the district.  The Antakalnis eldership is the second largest in Vilnius, with an area of 77.2 km². The Battle of the St. Lawrence involved marine and anti-submarine actions throughout the lower St. Lawrence River and the entire Gulf of Saint Lawrence, Strait of Belle Isle, Anticosti Island and Cabot Strait from May–October 1942, September 1943, and again in October–November 1944.  During this time, German U-boats sank several merchant ships and four Canadian warships.  There were several near shore actions involving the drop of German spies, or the attempted pick up of escaping prisoners of war.  Despite the 23 ships lost, this battle marked a strategic victory for Canadian forces as ultimately they managed to disrupt U-boat activity, protect Canadian and Allied convoys, and intercept all attempted shore operations.  This marked the first time that a foreign power had inflicted casualties in Canadian inland waters since the US incursions in the War of 1812. The Battle of Vilnius, Wilno, or Vilna was an attack by Russian and Cossack forces on Vilnius (Wilno), the capital of the Grand Duchy of Lithuania within the Polish–Lithuanian Commonwealth, that occurred on 8 August 1655 during the Russo-Polish War (1654–67).  The Polish–Lithuanian forces under the leadership of hetman Janusz Radziwiłł were defeated by the Russian army of Alexis of Russia.  It was the first time that a foreign power managed to capture the Vilnius Castle Complex.  The six-year Muscovite occupation that followed resulted in a major depopulation and a decline of the city for many years to come.  The defeat was one of the reasons Janusz Radziwiłł and several other Lithuanian magnates surrendered the Grand Duchy to Sweden at the Union of Kėdainiai.
