PNC Financial Services traces its history to the Pittsburgh Trust and Savings Company which was founded in Pittsburgh, Pennsylvania on April 10, 1845. Due to the long recovery from the Great Fire of Pittsburgh, PNC was not fully operational until January 28, 1852. It originally opened offices at Liberty Avenue and 12th Street. The bank was renamed The Pittsburgh Trust Company in 1853. In 1858, the company located its corporate offices to the corner of Fifth Avenue and Wood Street in Pittsburgh, where they remain to this day. The bank changed its name to First National Bank of Pittsburgh in 1863 after it became the first bank in the country to apply for a national charter as part of that year's National Banking Act. It received the 48th charter on August 5, 1863, with other later banks receiving charters sooner due to paperwork problems and the fact that the bank was already in business.
