What is the year that battle flags were moved to the capitol that began construction in 1819?  Answer the above question based on the context below:  The legislature voted in 1810 to relocate the capital again, and moved the seat of government to Harrisburg in October 1812 onto the land originally given by Harris a decade earlier. An additional 10 acres (4 ha) was also purchased from United States Senator William Maclay. The legislature met in the old Dauphin County courthouse for the next decade until a new capitol was constructed. A competition was held to determine the design of the capitol starting in 1816, which "was the first formal contest for [designing] an American statehouse". The designs submitted, including one from William Strickland, were rejected as being too expensive. Another contest was started in January 1819. Of the seventeen designs submitted, two were selected as semifinalists. One was from Harrisburg architect Stephen Hills and the other was from the designer of the Washington Monument, Robert Mills; Hills' design was selected. Hills had designed a "red-brick, Federal-style" capitol to "architecturally represent the function of democratic government." Construction began on the Hills Capitol in 1819 and it was completed in 1822.  The capitol's construction and subsequent furnishing was estimated to have cost $244,500. The Hills Capitol was visited by famous people, including the Marquis de Lafayette in 1825 and Albert Edward, Prince of Wales, (later King Edward VII) in 1860. Abraham Lincoln visited the capitol in 1861 as president-elect, and then his body lay in state there after his 1865 assassination. Pennsylvania's collection of Civil War battle flags, which were accumulated in 1866, was moved from the State Arsenal to the second floor of the capitol in 1872. The flags were moved, again, in 1895 to the Executive, Library and Museum Building. On February 2, 1897, around noon, smoke was discovered coming from the Lieutenant Governor's offices. By early evening, the Hills Capitol had been reduced to a "smoldering mass of debris".
