Fairmount Gardens, with the Schuylkill Bridge. This 1839 engraving, published in London, shows a view of the South Garden from the walkways that brought visitors up the cliffside to the overlooks at the height of the reservoirs. The fountain used the pressure of the reservoirs and was a a delightful refreshment in hot weather, and a wonder at all times. One anachronistic element of this engraving is the Upper Ferry Bridge, which burned the year before the print was published. Harding’s Hotel, a popular resort, is at the western end of the bridge.

The 1815 Engine House (shown here in an 1819 print) housed two steam-powered pumps that drew water from the Schuylkill River and pumped it into the reservoirs above the building, on top of Faire Mount. The artist showed smoke pouring from the south chimney, indicating that the South Engine was operating. The bridge just downstream was the covered Upper Ferry Bridge, an incredible 340 feet long, also completed in 1815. Designed and constructed by Lewis Wernwag, a native of Germany who had studied engineering there, the bridge opened in 1813. Formally called the Upper Ferry Bridge, it was also known as the “Colossus of Philadelphia” because — like the mythical Colossus of Rhodes — the bridge was held up only by piers at its two ends, with no intermediate supports. Made entirely of wood, the bridge was destroyed by fire in 1838.
