| During the excavation at the site of Three PNC Plaza archaeologists from Christine Davis Consultants discovered over 25,000 artifacts. The artifacts were found in a series of 13 brick-lined wells buried up to 26 feet beneath Fifth Avenue. The artifacts found at the site were in the time period dating from 1830 to 1865. These wells were used by Pittsburgh's earliest merchants and boarding houses. Several of the artifacts found at the site will be able to be seen in the new Fairmont Hotel located within the building. |
