The Lick Observatory building was designed by architect S.E. Todd of Washington, DC, in the Italian Renaissance style with the use of deep entablatures and moldings, and a pediment over the west door. The construction of the Lick Observatory building began in January 1880 under the direction of Thomas Fraser, James Lick's agent. To level the top of Mount Hamilton, Fraser had the top thirty feet of the mountain removed with black powder explosives. Workers then moved, by hand, an estimated 40 thousand tons of rock they had loosened. Masons built a kiln next to a clay bed near the summit and fired the bricks for the building. All of the heavy materials for the dome and telescope mounting were hauled up the mountain by wagon team and lifted into place with simple mechanical aids. http://www.nps.gov/history/history/online_books/butowsky5/astro4b.htm
