Places of Cultural and Historical Interest Chandler-Gregg-Hedges House Pennville has one of the oldest houses in Jay County, the Chandler-Gregg-Hedges house, built by Goldsmith Chandler sometime between 1836 and 1841. The house, which stands at 129 West Lagro Street, has also been owned by the Warren Gregg and Hubert Hedges families. Twin Hills The Twin Hills lie approximately 2–3 miles east, north-east of Pennville. Technically "moraines," accumulations of unconsolidated glacial debris formed by early glaciers, the hills range 100–150 foot high and are made up mostly of gravel and sand. Only one of the hills has been left intact, due to the high gravel content being used for roads and railroads. There is also a legend with Twin Hills as told by Sparkle Crowe. A young couple were having a picnic on the southern hill during the time of horse drawn buggies. For whatever reason the man killed the woman causing her ghost to occasionally be seen haunting the area. Underground Railroad and Eliza Harris Marker Founded by Hicksite Quakers, who were early abolitionists, Pennville and the surrounding area is rich in the history of the Underground Railroad. Approximately miles north of Pennville on Indiana State Road 1, near Balbec, Indiana, a marker was erected in 1923 to mark the site of the pioneer home of Jimmy and Rachel Silliven, an important "station" of the Underground Railroad. The marker memorializes the local legend that the real run-away slave, on whom the character of Eliza Harris of "Uncle Tom's Cabin" was based, stopped at the Silliven home on her way to freedom.
