Task: Question Answering
Input (English): Passage: Plans for a new building began to take shape in 1872 when the state legislature appropriated $100,000 ($ 2.1 million as of 2019) towards a new capitol building. This second capitol, built between 1873 and 1876, was a two-story structure with an additional first level that was partly underground; the total cost was $325,000 ($ 7.6 million as of 2019).  The cornerstone for the building was laid on October 5, 1873, during a ceremony that included a speech by Governor Stephen F. Chadwick and the music of several bands. Construction, on the same site as the 1855 building, was partly accomplished with convict labor from the Oregon State Penitentiary. Architects Justus F. Krumbein and W.G. Gilbert designed the building.Built of stone and five million bricks, Oregon's new capitol measured 275 by 136 feet (84 by 41 m) with a dome of 180 feet (55 m). The ground story was of native Oregon sandstone from the Umpqua region. The structure had a square rotunda on the interior that was 54 feet (16 m) tall. Also inside was a Senate chamber measuring 75 by 45 feet (23 by 14 m) and a House chamber of 85 by 75 feet (26 by 23 m). On the top floor was the Oregon Supreme Court with a courtroom measuring 54 by 45 feet (16 by 14 m) and the Oregon State Law Library, 75 by 70 feet (23 by 21 m). Also on the top floor was a viewing gallery for the House.  On the exterior were ornamental pilasters and two-story porticos on the east and west ends. The building included a lunch counter. Additionally, the building had mullion-windowed wings. The large copper-clad dome was constructed with an iron and steel framework. This dome rose 54 feet (16 m) above the rest of the building and was 100 feet (30 m) tall. The building was of Renaissance style with Corinthian columns on the front entrance and was patterned after the United States Capitol. At that time, the capitol faced west toward the Willamette River. The government began using the building in August 1876, before the dome was built. Originally, plans called for towers on both sides of the dome (a tower on both ends of the building with the dome in the middle), but they were left out to save money. Oregon's second capitol building stood from 1876 to 1935. 
Question: How many feet tall was the dome on the Renaissance style building with Corinthian columns?
