On July 4, 1829, a cornerstone was laid for the building at the intersection of Chestnut and Juniper Streets. It was designed by William Strickland. The second Philadelphia Mint, the "Grecian Temple", was constructed of white marble with classic Greek-style columns on front and back. Measuring wide in front by deep, it was a huge improvement over the first facility, in space as well as image. Opening in January 1833, its production was constrained by the outdated machinery salvaged from the first mint. Franklin Peale was sent to Europe to study advanced coinmaking technologies which were brought back and implemented, increasing productivity and quality.
